A good work I think! The colors are great, and the wings (especially the shading) are excellent.
I'm not a big fan of the bluish green glowing parts, though. I think it draws away from the original focus, not so much at the legs and waist and hands, but definitely at the shoulders. Glow effects, especially when they're a contrasting color, are extremely eye-drawing. I find the grow is distracting from the face, which is clearly a huge part of the overall character design. I recommend either toning it down the next time or removing from the shoulders all together.
Though its not all bad! I very much love the attention to detail you have. Little things like the sparks look great and add a lot of flavor to it, and the armor and wings have clearly been drawn with great patience.
