Check your insertion on the pectoralis to the humerus. It should flow into the arm and the deltoid should sit on top flowing with the clavicular head of the pec. Most of the bulk in the arm should be in the triceps not the biceps. 
The thigh development is wonky. You're missing the teardrop from the medalius, and it looks like the lateralis muscle is missing entirely.
Also bring the traps down and widen them out, they're sitting too high. Lots of other little stuff too. When you do your studies try going from muscle group to muscle group and really understand what's going on underneath. Look up some anatomical drawings and try to cross reference muscle groups on your photos. It should make it easier to translate things to your model. Right now you should primarily focus on looking at your thighs and shoulders.
