Keep working friend, at the moment it does not seem to go wrong, but you have to dedicate a lot of time so that everything goes well :)
In my opinion the bridge can be improved, but the lilac castle that is appreciated in the background is really incredible
This looks like a FFA map, really well build especially the trees! :)
Are those trees hand-made?
I would say practise more on a single player with world edit and if you want you could try to become designer and create beautiful maps for the community.
In one word... Gorgeous.
When I look at a build like this, I feel like a nub ._.
