Its called "Feed the Meter". The color on the character and the meter were ok, but the scorching background was bad. I noticed that the gradient looked better against the meter than it did against the character's purples and greens:

Removing the background was an improvement:

Now I can experiment with several different bgs, pick the best one, then add some details. I want to do some more watercolorish stuff in the bgs. What do you guys think?
