Granite Sketch (LEarning new Program)

I'm BACK!!! i guess xDD anyway, we just got a new program for our laptops at school. Art Rage. Pretty cool program. Think I'm going to be using that more than photoshop elements on my crappy computer xD So, to get to know the program I took a picture of the horse I'm using to learn dressage and just mess around with. His name is Granite and he's a chestnut "retired" grand prix dressage Hanoverian. Although I'm bringing him back out of retirement because he just doesnt seem to want to retire. xD So, there you have it. A sketch. I'm hoping to actually get a colored version of this. I already have the inked lineart done. Enjoy :3

Program : ArtRage
Reference Used : Yes, my own personal picture
