It's smaller but still big. Go with under 100px high canvas and you will see the difference.
But regarding this one, proportions are off, upper part of body is much longer than it should be, head is a bit big, and belt is too low which causes additional problems.
I would suggest that you block out basic shapes with bigger brush and don't think about small details until you define base right. It will be much better and it would save you time cause it's easier to erase or modify something that you spend only half minute on drawing than redraw part that took you hour or more to define.
Quick edit.
