I like what you have so far, but I'm not liking the battle box. It has a nice effect, but, the HGSS Pokémon cut off at the top. Now, that's all fine and dandy, but you can see the ground/platform, and there's nothing there. I would say either get the back sprites from Gen V and insert them, or get an opaque box.
As you can see, I'm currently adding the GEN V backsprites.
Aside from my nitpicking, I like what you have so far.
Considering the current routes on show are the first few routes, there isn't much interest in those routes, like in the official games. The first few routes are just fields and such. Later on the routes should show off the 'pizazz' you are looking for.
