It would be nice to mix up the types of trees (huge oversized red woods, ten times the size they should be with thin impossibly tall bamboo like plants that sort of thing).
Make it look more like an enchanted forests of myth.
But mixing in with the shot footage would be a real bugger (it's not like doing Hoth which is mostly wide open ice planes with mountains in the background).
Ewok totems would be nice too (as well as the nasty stormies on pikes I suggested earlier).
It's a shame the creatures in the Ewok films were done on the cheap because there were some nice designs (even if they were realised in really bad stop motion and men in suits, though no superfast bunny rabbits please).
I really liked the look of the Blurrgs for example but not the way they ended up on screen (I haven't seen them in the Clone Wars series but they look like the sort of thing that could be done well if the models were better).
