It looks really good. My only suggestion would be that you kind of smudge the edge of the colouring on the snail trail up his stomach so that it is not so uniform. It looks like you've painted a coloured stripe up his belly if that makes sense.
I disagree with celtic yautja, but I understand your reasoning.
Here's my personal perspective. I didn't buy the Bad Blood kit as a collector's piece. In no way am I a high end collector. I bought that piece because I really liked the concept and pose from Narin.
Do I feel shafted? No, not...
Looks fantastic Justin. There's a lot of detail in this kit and you've done a great job bringing it all out.
I'm presently trying to paint mine white too, but it's not working out very well at the moment :unsure:
I love the blue.... lighting.
Very nice indeed. The skin tones are very muted which you don't see often.
I am currently debating how to paint my Bad Blood up and I'm finding it very frustrating because I change my mind every five minutes.
I will be happy if mine turns out half as good as yours.
I don't know if this will help you, but here was my tutorial for painting a Predator from the first movie.
There might be something in this thread that will help you.
