proportion catching

Start off like you have been doing, but work with smaller lines so you can get more detail in. The shoulders are a bit wide and the arms are long. Everything else is alright just work on those things and then making it look good.

When you're working on proportions, sometimes it's better to ignore the clothing and try to draw what you think the body looks like underneath it.

A tip for the shoulders: draw their construction circles overlapping the torso construction circle, since in real life, the rib cage is narrow at the top, and shoulder sit partly on top of it.

Your proportions look pretty good otherwise, so I think if you can figure out the shoulders, you'll see an immediate improvement!
