Nicely done, lots of color :D I love how the clouds turned out! A little trick to grass, that I use, is the smudge tool. After the grass is painted, I blow up the smudge tool to huge and goof around with the settings until it looks good. This also works good for fire :) Fire, safe pic I'd recommend just clicking random tools sometime and goofing around, there's tons of crazy junk!
