Nice outfit!
Try not making the face so fat at the left side tho, looks a bit weird
Also you can fix the right arm by following the left arm.
I'll try to show you incase you don't understand
Your right shoulder is higher up than the left one, it should be in the same height, so try to either make the left one higher up, or the right one lower.
It doesn't necessary have to be in exact the right height, but have atleast 1-2 pixels from each arms.
I tried, but failed a little
Forgot to do the shoulder line, but I don't have time right now.
Hope it helps, even if you already know this
(I know Limos posted something like this)
