Wow! This is really stunning! I like the colour pallet you used here. Maybe if you lightened the background a bit more the depth of this chamber would be even more visible.Keep it up : )
... and maybe a bit of fill light on those blackest of foreground elements - just a bit of bounced light to bring out some additional texture and detail - not too much, but enough to sell them as solid and three-dimensional.
thank you :) yeah, its a little blurry at the moment too. ill work on this a little more
