One this i will say is that you might wanna learn collision because that is gonna hard to look around in udk without. but so far it is really nice. I would like to see maybe a little bit of overgrown like vines climbing walls. I have a feeling that will help out the feel of it. :) watching this now!
I really like the concept and you have some really nice props and lots of cool foliage. However I feel like the biggest issue here is composition, it feels like it's hard to get a nice angle for the shots anywhere in there. It's just too crowded. You don't really have a central piece from every angle that the eyes get lead…
