More #riso test prints. Trying to print up all my central park pollinators. I didnt draw these specifically for riso printing so the cymk ish separations have been super fiddly. Using blue, yellow, fluorescent pink, and brown inks

Working on a new #riso print today. Hunter green ink turned out darker than expected so had to do some tweaks. First layer printed with yellow and raspberry

Hi #PortfolioDay
I'm a freelance science and nature illustrator from New England. I love drawing native species I find on my walks, especially if they're weird and warty.

Dream job would be to work on a non-fiction picture book

Riso printed Monarch butterfly on a salvia flower, with central park in the background Caribbean fish from the New England Aquarium, with Thomas the moray eel in the center

Had a great time sketching at the new york aquarium the other week. Could really only draw the sleepy ones while I was there so I maxed out my phone storage with reference pics and had fun with posca markers at home.

Another #pollinator closeup. This time a cabbage white butterfly. This might be my favourite flower in the series, and I had fun sneaking my friend and their dog in the background.

Happy #Pride 🌈 Vector illustration pack of native plants and animals in every colour of the rainbow. Made it a few years back, and if you're in Maine might see it again this year 👀

Really big lichens or a really small hiker? I’ll let you decide

Be working on this one for far too long but I present to you "Central Park #Pollinators," based on bugs I saw in the park last summer. The plan is to print it as an accordion book but it also works as a big ol sign

Fantastic ending to Baroness Kidron's speech in the House of Lords yesterday, which led to the government's defeat on AI & copyright.

Speaking the UK's creators: "Their property, their labour, is worthy of your protection - because apart from anything else, it is not ours to give away."

Folks call your Senators now!! A ban on any state laws on GenAi for 10 YEARS is gonna do unthinkable harm!

For those of you wondering what to say here are two posts you can use to build your own script (use alt script to cut and paste)

Need to find your representatives? Here you go:
5calls.org
User Zachary Berger recommends the following script: "I'm a constituent in the congressperson's district. Al regulation is life or death for a lot of the Congressperson's constituents in creative industries, please make sure the section in the budget reconciliation bill banning Al regulation doesn't pass." User Karla Ortiz gives information on the bill so you can point your senators where to look: Call your representatives! Tell them just yesterday (R) Congressman Guthrie added a new text to the Budget Reconciliation bill to BAN GenAi regulation in the states for 10 years! Hell, point them to the specific section: TITLE IV-ENERGY AND COMMERCE (Part II: Al section, (c) moratorium)

So excited it's vernal pool season again. Eastern red #newt and some of my favourite moss and lichen (Peltigera) I've seen in Vermont. Original digital illo and #riso print, using my own funky spot colour separation.

#sciart #lichen #illustration #art #nature #procreate
Original digital illustration. The lichen is definitely a Peltigera, inclined to neopolydactyla cause it has some pretty long rhizines vs polydactylon, can post ref pics if anyone wants to help id Riso print, using blue, orange, and yellow. Orange drum was a lil broken so got kinda stronger than expected but I kinda like the warm vibe.

More #riso prints from my #lichen close ups series. Both from the genus Cladonia, the one that looks more fingery in the sub group Cladina. Fun fact the tips are dark with the same melanin pigment we have as sun protection for new growth

One of my favourite illustrations from last year, showing fish I saw on a trip to the new england aquarium. Originally made it for a two colour riso print but have had fun rearranging bits for some mock editorial layouts. Need to draw more fish
