Nice colors you used! I especially like the clouds. You have a fairly small canvas containing 41 colors altogether, but many of them are similar so you possibly could've utilized your pallette a little better. Still, your idea of form in the composition is well thought out! With your creativity who knows where the wind will take you! 
@DexRunner, thanks very much for the advice and encouragement, I really appreciate it! I just started arting and am still getting the hang of color picking, so I'll definitely keep that in mind. I think i might have used way too many colors for both the umbrella and the grass..
