I’m trying to make it look like he’s wiping blood or smth off his cheek but the arm just looks wrong and I’m stuck :’>

I love the way u draw the stomach/ chest it's so satisyfying

One thing I notices is the arm reaching up is to short, and there's no bicep there

Thanks! I tried to fix it but I feel like it’s still…off 🥲

Keep in mind the length of the ribcage (green) is the same length as half an arm

I think I had a guide for this somewhere but I deleted it hold on too

Ez arm proportion

Oh that helps a lot, thanks!
