It looks like a hydra spawn to me, tell me what it looks like to you?
Stop being so rude all the time, can't you atleast write a nice comment telling me what's wrong?
i agree he didn't have to be so blunt and insulting.
A half finished hydra spawn, could be used at any server
Although i will give you what's wrong and what to change. etc
There are no borders on the mountain, as in round the grass (it's good you're using raw tho!)
The jungle nature doesn't fit there unless you place more overgrown nature. I see no grass what so ever.. but only use the 2 smallest sizes imo.
Try to avoid the trees with parrots.. look funny imo (only in pirate climates). Your bordering of the mountain at the bottom - try to miss the odd few on straights to make it look more realistic. Not bad mountain attempts btw
regarding the waterfall, remove the mountain border on the corner and place two watefalls there facing v and >. believe me it will look better!
The water borders on the mountain would be the stone bordering.
the fern leaves look odd spammed in 1 spot like that. (try to vary the nature more)
if in a jungle environment place more dirty rocks (mossy) and more overgrown logs opposes to the plain log.

good luck.
The bridge needs supports etc.. Tip: go onto raw > architecture, find the wooden supports and use small diagonal attachment piece (the single block) and place 2 either side of the north side of the bridge. Then use the long wood pole with the attached block on the south side hidden in mountains (alt+click) it will look more realistic then
