...the advice I got on drawing with crayons would change the quality of my traditional colouring so much.
The lineart isn't really important. All I know is that this is Leo (yah yah, skin tone's off) and he's naked because I felt like it. What he's doing is unknown. Also notice how inconspicious the lineart mistake on his right collarbone is.
The way he's cross-eyed reminds me of how KameChuu draws him
