amazing piece Nao, loving your art
the work you did to achieve the metal texture is great
Such gorgeous texturing (in both color choices + ""dither"" patterns) on the metal!
Only criticism I have is I had to change background colors to notice how gorgeous it was too, I barely noticed it like that. 
incredible stuff all around
Got nothing else to say other than damn, this is NICE. Love the gradients on the wings.
I had to look this up to compare, and... wow. The color scheme you used merely exists, but you made it sing. The way your silvers blues and golds are all working together is phenominal. I wanna check this game out simply because this is such good art.
This is really some top notch pixel art
