If you want, i could sketch out what i mean on some paper, idk if it was a good explanation. I do like the composition of the piece, though!

Hey i think it looks great, id love to see the pre sketch you did for this, im still learning digital art as well but a good art tip might be drawing out the shapes you want first bc the cock kinda just goes into the mouth maybe try sketching the shape of the cock first then the mouth around it.
