I Fight for this?

#3 in an apparent series of Sonic characters. I realized that probably 80% or more of my drawings are of my own (or other) fan characters. In fact, I almost draw NiGHTs more than Sonic. Unlike Peaceful Forest http://www.deviantart.com/deviation/28701206/ or T2K http://www.deviantart.com/deviation/29356493/ , this one offers little coloring experimentation. I used the Bezier tool with Pen for most of the outline, and stuck with Watercolor 2 for most of the coloring. The backdrop would have been more elaborate, but I was not in the mood for drawing. Quite ashame actually, as Knux is one of my favorite Sonic characters. Truth be told, He and Shadow are tied as overall favorite, followed by Tails, then Sonic. Nack is easily my fav misc. Sonic character, but I digress. He looks upon a Master Emerald shard, contemplating the worth of his eternal quest to guard the emeralds.
