This is a very well done piece. The anatomy is flawless, portrayal is top-notch, and the background, while simplistic, compliments her character well. Samus has long been a staple of awesome and, if you will, badass female characters in the video game world, and you bring something sexy in this drawing without losing her charm. The metroid is a nice touch, and the pose is something that one would expect to see from Samus. As for the coloring, everything seems to be correct. It's not heavily shadowed, so her skin stays fairly light, complimenting the background. The coloring on the metroid is also well done, and her hair has just enough shading to give a lot of detail without taking the focus off of her body. The lineart is a good thickness, I noticed that you use a bit thicker lines than some artists, but it suits you well as you make it look stunning. The only thing I have a slight issue with is her eyes. They're a little too angled in my opinion. Also, if her skin was shadowed more, it would accentuate her curves more, but the lines do a great job of that anyway. Bottom line is that this is a wonderful piece and a sexy homage to a long-loved character. Amazing job, and here's to many more!
