This is a drawing that Tony did for me at BronyCon of my OC, Bluetec. The original is a black and white drawing on a type of card stock. I took and made a copy of it and colored it in using colored pencil. I will post the original as well shortly as a comparison.
 
I wanted to leave the original as it was but was curious as to how it would look filled in. Its not the greatest job by me but its definitely not the worst. I may make another once I find my other colored pencils and try my hand at it again with a wider palette to choose from instead of just 3 colors.
 
Credit goes to Tony for the original drawing.
