1. ThatSteveGuy - I FEEL like this is a retro pinup, nice job.
2. Domtopia - I like the fact you didn't go overboard with your saturation, it would have been easy (IMO).
3. Sugar - Nice and tidy and good use of texture.
Kodabble, I felt you lost a little bit of clarity somewhere along the long, and it looks to me like it could use a couple of hours more of refining - blending a bit more and adding detail. It's good, but doesn't quite feel finished to me.
Midscrawl, so close, I love the clarity of it (and like the simple but effective background). I also like your creative use of anatomy or the arms, they look like there genuinely is a bone and muscle structure that fits together in a coherent way. However, the only thing that stops me putting yours at first place (I had a job choosing my preferred order) is that I feel like the heads are out of proportion (both are slightly too big IMO), particularly the one on our right which looks slightly bigger. Now I know it's hard for me to make a judgement on the anatomy of a non-existent creature, but as I look at it, I FEEL the image is top-heavy. I can't help feeling like she'd struggle to walk wthout falling over.
Excellent entries guys, I had to be picky to choose my ranking. I wouldn't want to be given that brief!
