Here's your score
I wish I had some idea what causes certain submissions to have no ratings on them. Of course, we always have the reviews! I thought this was kind of one of your weaker entries, but it's still well done. Its strongest point is probably how you use these sketches so well. It reckons back to the old days in the Renaissance period where people like Leonardo Da Vinci showed off their art work. Hey, we're the modern day Leonardos!
It would have worked better if there was more background. Then again, that was more of the point with the sketches. The colors are pretty well done and I really understand where you're coming from with this. The bright yellow colors are easily the most elaborate. It doesn't really seem so steampunk, more like standard fantasy.
