I do not think it is actually possible for me to convey with words the complete and total awesomeness of this commission. Being familiar with Key Gear's collection of characters, the claim that this captures this one perfectly is the Oxford definition of an understatement. Everything about this piece looks fantastic in my opinion. The background perfectly supports the pony. Its detailing is superb, and the color spectrum can be summed up in one word: fantastic.
As for the mare herself, I think I will restate the reaction the first time this piece was seen. "Holy crap, look at that mane!" In addition, I think it's important to state to the general audience that I have heard the background story of this commission's origins. You were essentially told, "Here's a reference, and she's a pretty pony." You took those things and made that *points* piece. It really is a credit to you as an artist. You did a fantastic job and made your commissioner a most happy individual, making this work a complete success.
