So as per the ELOQUENT-EQUESTRIAN contest I have to write a critique and I thought I would write one for my dearest friend!
You know that I admire your style, I am jealous that you can do such amazing work in Gimp. I personally love the simplicity of the design, the natural colors makes it very easy on my poor eyes! XD The hair looks magnificent and it is apparent that there is some wind, but just a small amount. The fading white to black background looks great, and it is easy to extinguish the grasslands from the foggy sky. The only thing I would suggest is to lighten up the motion blur on the sky, just to make it a little easier to look at. :3
