Peekaboo! I see you!
#pizzatoweroc #oc #art
Poster art of Jesteroni, legs posed as if he's mid-walk, staring wide-eyed at the viewer with his hands to his face, pushing his cheeks together. His mouth is slightly agape, seemingly surprised. The backdrop is a purple gradient with the same Jesteroni image over top of it, with a faint star pattern.

Behind them is a pink gradient backdrop with small stars, and a yellow and orange tile floor.

I wanted to draw my own take on Were-Noisette.
#pizzatower #pizzatowerfanart #art
Artwork of a top-heavy, monstrous Noisette with noticeably muscular arms, based on the Were-Noise concepts from Noise's Big Break, a planned spin-off of Pizza Tower. She has an angry expression on her face, her eyes wide with fury as she glares at the viewer, jagged teeth protruding from her mouth. The ears on her mask are longer and sharper, her pink pinafore has ripped, jagged edges at the skirt, and her white undershirt is also ripped at the sleeves.

My entry for #FriendshipGames2025!
"Let's go, Shadowbolts!" 🖤⚡

#mlp #mlpfim #mlpeqg #mlpfanart #equestriagirls #art
Artwork of Sugarcoat, to the left, and Sour Sweet, to the right, from "My Little Pony: Equestria Girls - Friendship Games." Sugarcoat smirks, one hand behind her back while the other is on her temple, making an L sign. Next to her is Sour Sweet, who is winking while her tongue peeks out of her mouth. She has the back of one hand placed on her hip, while her other hand is also next to her temple, making a similar gesture to Sugarcoat. The backdrop is a pinkish-violet to pastel pink gradient with a candy and sweets pattern, with the word "Sweet" appearing occasionally. Surrounding the image is a white frame.

A screenshot of a Strawpage gimmick. It's a drawing of what appears to be Gaster from Undertale and Deltarune. He has an unnerving, wide grin on his face while he raises his hand, seemingly waving at the viewer.

Mach 3 concepts for @pizzatowerhead.bsky.social
Concept art of Pizzahead's Mach 3 with notes included, taking inspiration from Nimble Nibble's original concept at the top left. A Top Speed patch from Kirby Air Ride is also pictured next to it. There are 4 different iterations with subtle differences, such as arm positioning, how much his head and body lean, and different hand concepts at the top right, like an outstretched pointing hand. The first one has a note that reads, "Body curves more? Exaggerated shoulders." The second one has a note that says, "Subtle downward lean? Shoulder curve + arm?" The third one simply says, "New hand?!" with a concept that has a different hand than the others. The fourth one says, "Uhhh???" with another concept with minimal differences. An additional note, pointing at the shape of his body reads, "He's shaped like a bean... or a hot dog." At the bottom left is a doodle of Tenna, meant to fill negative space.

I was asked to ship Tenna and Jesteroni for some reason... Well, I guess everyone loves a good crossover episode!
#deltarune #deltarunespoilers #pizzatoweroc #oc #art #ocxcanon
Artwork of a crackship between Mr. Ant Tenna, from Deltarune Chapter 3, and my Pizza Tower OC, Jesteroni. Jesteroni is hugging Tenna, nuzzling his face into the larger man's chest, while he plants his feet on the other to hold his place. Jesteroni excitedly exclaims "I love TV!" written in all capital letters. Tenna, clearly flustered by Jesteroni's displays of affection and him declaring his love for TV, smiles sheepishly while clutching his head, saying in response, "Y-you do?!" The backdrop is a pink gradient with a repeating heart pattern.

assorted Jesteroni doodles
#pizzatoweroc #oc #doodle
Various sketches of Jesteroni with different expressions. On the top left, his arms are crossing his body, his fingers pointing outwards. He looks somewhat surprised, with his eyes open. On the top right is Jesteroni with a flustered, seemingly embarrassed expression. One of his eyes is opened a little, another tightly shut, as he gazes up sheepishly, forcing a grin. His finger taps his face. On the lower left is an annoyed looking Jesteroni, his arms crossed as he looks to the side with a raised eyebrow. At the bottom center is a smiling, inquisitive Jesteroni with a finger to his mouth. His tongue is sticking out as he raises an eyebrow in intrigue. Finally, at the bottom right, is Jesteroni with his hand raised, his pointer finger extended upwards. His other arm is behind his back as he grins proudly, as if he's about to explain something with confidence.
