This really surprised me!
The wings has some really cool details, I weren't expecting that at all!!
And the details you have written down about where it will bend and how much makes this even more cooler!!
I wish there was some more details on the pony, just to make this pop out a little bit, but hey this is amazing just the way it is!!
I like how you created the metallic feeling really nice!
But now I would like to know how she could fly with holes in her wings, but hey maybe that's magic ;3
