it makes sense and i draw with a mouse and yes some kinda tablet and the edges i think i can fix

is this drawn with a tablet? Either way, cool work, I have never been good at just drawing with a pencil....nice work..the only suggestion I would have is....the margins of the muscle groups are hard edged, maybe make them a bit less pronounced so the edge of the muscle is softer, does that make sense? especially the muscles on the left side of the image (right side of body)

okei i will try

I think it needs a bit of shading so it looks like the bent arm is in front of the body and not a 2d image. Right now it kind of looks like the forearm is growing from the shoulder.

p.s he gots a 4 pack and i think i should change it:s
