Looks really good Glassman. I think that if a wilderness scene is created though, the forest would need to be less dense, that way we could include more customs in it, perhaps a Rebel bunker, a landspeeder, etc. And some sort of creature or two. I do like the idea of a tall Imperial tower.
As for a swamp, I'll take some pics of something I have that might look really good for trees... here's a sneak peak at what I mean -

That's not the best pic in the world, but on the right side of the pic you can kind of see the tree I am referring to, they are from aquariums (can get at Petco). Kind of pricey, but they look awesome in person.
We can also use real wood too... sorry for another photonovel pic, but here's what I mean... real wood and also that fake shrubbery stuff can look cool on a forest floor -

On the idea of dinosaurs... I love dinosaurs, but straight up dinosaurs I think would look out of place. Not that this is the ideal creature, but for example I think some sort of beasts of burden native to the planet, kind of like this might look good for it -
