It was hard to tell what you were going for in some places but these are just suggestions not rules anyway.
First, the sideview of an eye is probably something you should look into (was he supposed to be looking at the viewer or ahead, not sure?).
Eyebrows need some foreshortening in profile.
As far as muscles, there wasn't any indication of the sternocleidomastoid. It's the most important muscle of the front/side of the neck to be aware of.
Your muscles are a bit bubbly and don't indicate underlying forms that strongly.
Lack of indication of the pollicis muscles of the forearm (doesn't need much but slightly bringing forward that part of the forearm is good).
The pectorals bump is a bit too high.
The triceps usually should form a flatter tendinous region on the back of the arm.
The anterior superior iliac spine of the pelvis is a very strong useful landmark to indicate.
The knuckles should curve a bit more.
Lastly, a couple extra lines around the tip of the dick can help to indicate it's form.
