More on Covers... the Concept

On talking about how important covers are, I've been wanting to redo the cover for The Summer of the Frogs for some time.  I believe the cover is affecting my sales or lackthereof.  It's a good story; it deserves a good cover that will draw people in.

After mentally going through several concepts, I went to sleep with an idea floating around in my head.  Upon waking, I still liked the idea, so went forward with nailing the concept down.

Right now, it's in the sketched concept stage with a generic font slapped on.

But before I go forward with the hours and hours of tedious coloring, I'd like to get some feedback.

Let me know what you think of this concept.  I'd deeply appreciate it!
