That's pretty damn good, However, I don't think the character's center of gravity reflects the weight that the ornaments on her back would bear, and I'm also wondering how she would bend her elbows, them being covered in a solid piece of metal armor and all.

The colors, lighting and background are all awesome, on the other hand. The lineart is impressive and the armor design is interesting.

I LOVE how the light is treated. But I really have a problem with that manga design. I think you could (and should) dig way more into your own personal style.

wow. i really love this. the coloring & shading are outstanding
i really love the details on the armor . background is awesome aswell
