Nice Dexsoft environments... ;-)

You should fulfil the environment with objects like barels, torchlights and even maybe with moving objects like people or animals walking around. Also you should overwork the lighting. I like the screen with the massive blue light, but this is just a beginning. You should use different, warm colors and mix them up. Just look at this screen from Oblivion. They use a green ambient light and mix it up with the warm orange from the torchlight. Looks quite unspectacular, but pleasant.



Another overall question. Why are you using medieval stuff? I personally think that toy-planes rather match to a child`s room or a front garden than to a dungeon...
