i reconize alot of stuff from other maps in this, the rock texture needs to be scalled up for sure, maybe aligned to wall to if you havent done it yet
maybe some more plants, plant 3 i thought is always cool and give it some bigger drawscales and lower ambient brightness 0.75 or so
and let those torches give some more light, better light shadow contrast would be nice
but it looks nice allready, show more pics
