Hey
As much as the new MS Paint rocks, and as slow as the work goes with it I recommend switching programs. I know for a fact, as a fellow Paint worker, that it is addicting and fun but you must, however reluctantly switch to Gimp2. Gimp is free and slightly complicated but when you get into it the work is a million times faster and sometimes more fun, you can still do pre-coloring with Paint too, it's what I do, it will improve the sky and water, just play around with it =D [ http://www.gimp.org/downloads/ ]
