Gorgeous painting! It looks so incredibly real that from the thumbnail it looked like a photograph! I love the lighting on her skin, it literally makes her glow. And the detailing in both the feather and in her hair is amazing. Stunning portrait!
You are insanely talented, it's not very often that you find great concept and composition along with incredible technical skill, even more impressive is the scale you work on, a lot of artists would be intimidated at trying to achieve this level of tone and detail at that scale
