I like it!!! I like your proportions a lot. Your poses seem a little stiff, so just loosen up your hand and don't be afraid to make wide/slim strokes. I struggle with the same frustrations and I think it's very easy to only see our mistakes. Your poses are very clean and precise. Just keep drawing:)
These are really good. They're very proportional and I can tell you know what each part of the body looks like. The only suggestion I would make is to use less straight lines, as straight lines limit flow and make poses look stiffer. But these figure drawings look very aesthetically pleasing:)
