This image was created for the Moddb Concept Art Competition. You had to draw an image based on a pre-chosen theme, and I chose "Alien Experiment".
Grand Prize is a $3,099 Alienware XPS PC. It'd be totally awesome if you'd vote for me.
This is the longest I've ever spent coloring any one picture. I worked on it for over a week solid. Generally, from sketch to completion, most pictures take me 8 hours on average.
This probably was closer to 20-30 hours.
