Well it's decided, you guys are all awesome. I really appreciate your feedback and help. I think that the first idea may have to be revisited at a later time. I think having a bridge leading toward the viewer, and possibly a traveler in the foreground like @TessaW mentioned. But I think it will need more work and time then I currently have for this piece.
So it looks like frog in the rain wins this round. I think he will be holding the umbrella for a tiny mouse or bunny friend, who is less fond of getting wet. Maybe, up the scale of the mushroom door so they could actually fit inside. Should be fun to see how it all comes together.
