Anatomy issue?

[civic glacier]

I want to change any mistake before i finish the drawing. I dont know why but the anatomy for this picture seems a bit off. I want to learn anatomy and i have been doing it for the past 3 days. If anyone has any tips pls do help out.

Hi, I would start by looking at two things. Love the face and midsection and legs. As for what looks off, let me toss in my own observations.

1. Arm length ratios, the forearms look out of proportion as there is no foreshortening on the upper arms as they would come away from the body in that position.
2. The positions of the arms with touching elbows. Try this move yourself and see if you can hold it. You can pull this off with ease if you were leaning on a table and your elbows resting on it, touching as your shoulders would have moved into different positions allowing for the extended flex. Standing strait up with your arms at a your side then trying to capture that pose is what looks off. When trying this position you will notice your shoulders and upper chest "Curve inward" as the shoulders are pushed forward and the pectorals contract allowing the arms to reach those positions.
   This is just my opinion, hope it helps.

Perfect! That explains perfectly why the proportions are off. Thank you so much!!!

I decided to do a pose and take a picture as a reference. You are right and I'll consider that next time.

That's good! Just keep basic proportions in mind
And to measure proportions u can use the tip of your pencil then place the same length the otherside
