I have to say, when it comes to capturing a grand and significant moment, you are sure an expert of the matter.
I must say, I love the sunset tone you have given into this piece of art. The character is very original from head to toes, I love how she looks very thoughtful. It gives her a sense of wisdom and coolness too, which is from my point of view something that enhances a character's beauty.
The scenery is breathtaking. It doesn't seem to have much details in it, and yet the colors in it are what makes it so alive and I believe you have achieved that perfectly.
Oh my gosh, this is beautiful!!! I love how you did the sunset and this line-less color layers for the background. I does a wonderful job pf setting the mood without drawing attention away from the character! Great Job!
