This is stunning! You should totally offer commissions like this! This HAS to be one of your best pieces so far! The shading, the brilliant, almost electric blues and purples are amazing! The detail and pure originality of this piece are brilliant! Bravo! *applauds*
I might be wrong, but is this about how everyone once in a while disguise ourselves behind masks when we are out on social situations? If it is, i find very interesting the idea of a very shiny and pretty armor, but that in the end is just another mask!
I love the whole content in this work how she hidden because of the lights. I truly love the asymmetry balance on her mask and the dress, I find it very eye catching yet have some bizarre to them by the design on the mask/dress as well. The shading on her skin are very smooth that it shows the detail on her neck, collarbone, and around her face as well. Also, I love how you have a great balance of have that glow effects on her hair yet still could see the details and the background are just simply colorful without been too much which I like.
All in all this painting is very beautiful, keep up the magnificent work.
