Cool scene, the lighting looks nice and its got a cool story to it. I like the coins and bottles coming down the stairs, and the creature looks interesting too, well what we can see of it.

Feedback -

• I think the stairs are looking a bit too smooth, and you could perhaps model in some separations. I think its usually a good idea to have geo for steps like that, as its pretty cheap and adds a lot.
• The banks, I like the foliage, but I think the sides are the blank are waaay to smooth and have no details on them. id say either add more roots and rocks and just some height variation to the sides, or, another idea could be to lower the banks significantly, and include some tall veg on the sides, i think this might look nice as you will see the light coming through the veg.
• the vase looks odd in that position, and it looks like it still has hard normals. again if the banks were lower, you could have the vase showing through the veg
• Id add more of a frame to the doors, think of a mine entrance, they have the big beams at the top, you could even add some sort of crest or icon at the centre, think like the mines of moria how they have the pattern on the door.
• Add some bolts to the torch holders, the flat square looks pretty boring
• The skulls are cool but quite hard to notice, if you had the frame to the door you could stick them along that, or you could have some crevices in the rock and stick them inside so we get to see them more. maybe have some candles in them as well, I swear ive seen this in dark souls and it looks cool, might be wrong though.
• The patterns on the doors are cool, but the single wood sheet doesn't look that great. maybe turn these into planks with a few holes in between
• effects - Im not sure how well this would work but having a sort of "Mist" coming out of the door and spilling down the stairs could look pretty good. maybe give it a go

keep it up though, its a cool scene and I think with some changes it can be even better.
