3 Marvel girls coloured

Hey peeps, it's been over a year since I submitted any colour work, and that's because I haven't coloured anything. I've been totally swamped with work.

So lately I've been wondering if I even remembered how to colour anything and to relax a bit at the end of a long working day I decided to pick up a piece by and colour it. I started following Paulo a few months ago and I've been itching to colour something of his.

I tried out a few new things to hopefully enhance the image and I would love your ideas/feedback especially on backgrounds for these character pics, because that's a part that I always have trouble with.

Each lady took me 30 to 45 min and I used Photoshop CS5 with a Wacom Intuos Tablet

Thanks

EDIT:
Thank you to everyone for such incredible feedback and all the favs and watch. Unfortunately DA won't let me thank all of you personaly, because of SPAM issues
