I love the style, of course, but I think the thing I like most here is how you've portrayed her with a more realistic body! Her torso is wider, breasts aren't ridiculous or the main attraction, arms look like they have reasonable muscle tone, etc. It's very nice!
That is what it is all about, experimentation and honing your style to what you want. Just play with it till you find what you are looking for. I have never had my own consistent style to make my work stand out, but I haven't experimented enough to see what I could come up with. It's something to work on.
Interesting way to use the colors. She seems to be in some kind of stasis-movement (or something like that). Good work on the background texture, but it might be better to graduate the tones or colors so that her zero suit and the background differ more from one another.
Yeah, the real expensive one. But it's expensive because it's really detailed! Well, I do have a Halo collectible, the Master Chief helmet from Halo 3's Legendary Edition. It looks good. But there are some crazy figurines. For instance: [link] Ready to drop $425 on that sexiness?
