The image is great, but the jacket indeed makes her look a little over-sized. You could have adjusted the angle of which you took the photo by taking it from a higher angle to make her head more proportionate. I'm not sure what lens you used, but standing further away and the use of something like 150mm would also do wonders.
I'm a noob and know nothing...but I like the cream sweater one better:blushing:
I HATE the jacket:x
If you don't like the cream sweater, could you not just change its colour in PS? also the red top?
