This work really demonstrates your technical skill as an artist. The details on every inch of of virtual canvas bring the picture to life, from her hair to her dress, the fire in her hand and embers blowing in the wind. There's also a very believable sense of motion from left to right.
I like the subject matter as well. You show our fair princess as something more than a helpless victim needing to be rescued by Link. She's looks confident and competent, like she really belongs on the battle field. I would not want to mess with her at all.
If I had to criticize anything, it would be that the damage to her costume is a bit excessive. It seems as though every piece is effected, her dress, shoulder armor, tiara, even the wrap around her hair is coming undone. While it's believable all those pieces could have been damaged in an extend fight the fact that they each of them still has bits flying off suggests to me that they all happened at the same time, which I find to be somewhat unbelievable and excessive.
One more thing which is not really a criticism, but a preference. Her eyes seem kind of dull blending in and having the same orange tint as the rest of her face. Eyes are the focus of a face and I prefer them to stand out somewhat. If they had been a noticeable shade of blue it would have added some nice contrast and more character to her face.
My heart stopped and I died. This is...awesome--in all original respects of the word. Awe. Some. I just...the clothes may be tattered but the princess is still firing up her laser gu--powers to kick some ass! Just wow.
