The mockup is cool, but i think the trees behind Joey could be a little bigger. And I think you could try removing the outlines from the tree too.

A mockup ta legal, mas eu acho q as árvores atrás do Joey podiam ser maiores, e acho q você podia fazer um teste e tirar o outline delas.

I know that you used the black outlines to emphasize the objects in the foreground, but they still seem a bit out of place to me. I would suggest removing the outlines from the trees behind Joe [and maybe those rocks behind our friend with the toothy grin], though - since he does not directly interact with them (I would think). I do like your holey textures, though.

Polonius: Very like a whale.

interesting mock-up
