Not bad for a draft. I'd change the leaves on the tree to something a bit more realistic (don't like them as they are). That, and I'd alter the angular relationships between the swooshes a bit, tilt both the blue one and the brown one's together so there's a bit more white space beneath your text. Then maybe make the text taller (it looks too square-ish). The sun will appear to be a bit "higher in the sky" when you're done.

Just my opinion...
