Trying to learn anatomy; arm study

[Defunct]

I'm slowly studying human anatomy. So far I've only "covered" most of the skeletal and muscular structure of the arm. Did this "study" and though some of you might take a look and see if I got it all wrong :

a "handmade" copy of the photo - might help me learn better rather than just using the photo

labeled some of the most visible muscles, definetly not sure if I got the right - it's difficult! (sorry for messy writing, no tablet.. also take notice that I'm not a native english speaker :p)

Just my 2 cents, but...

The elbow joint should be largely defined by a wide pair of bumps -- the condyles at the distal end of the humerus http://www.bio.psu.edu/faculty/strauss/anatomy/skel/humeruslow.htm (see how I throw down the lingo? I got it from that web page)

Those two bumps are important bony landmarks in determining the orientation of the elbow joint. In your drawing, you've made it a bit vague, and given all the bulk of the elbow to the ulna instead of the humerus.

Also...

You've pulled the scapula (shoulderblade) too far around. It should be half on, and half off the rib cage -- not completely off the ribcage and under the deltoids. In essence, you've made the humerus too short.

That's my impression, anyway.
