The shot of the broken arm works well in a comic scenario, but here it feels off and disrupts the visual flow of the peice, it's very distracting. The focal point should be his wrist.

You can achieve that by creating a more dynamic composition (try looking at some poses!) The profile/side composition does'nt work well when you need to communicate movement.

your techinical skills seem on point! Great anatomy, I love the lizard's face and expression, haha. Try to avoid the "?" graphic, you have a good expression drawn and you don't need that!

Overall good effort, think about composition more and your anatomy skills will show much better!
