Noice! Imma give you some feedback whether you like it or not
First the screenshot. The player model is superb and the terrain is great, especially the curved edges. Reminds me of @zzuegg's Ludus Caelestis.
The ferns look a bit out of place with their bright colors, multiplying their color by itself and by 0.8 yields a much better result imho:
Though looking at the video it's apparent that this is more of an edge case than the whole game as the foilage usually fits in quite well. The plant edges could still use a lot of AA.
Now the main thing that bothered me about gameplay is the character placement. He is getting in the way of whatever it is you're doing at any moment and doesn't serve much purpose. The way to solve that is very simple, just position him more to one side of the screen.
That way you get a more unobstructed view of what you're doing and can also zoom in a lot more without loosing sight of what's directly in front of you. I.e. Skyrim 3rd person cam.
I see you have a 1st person view mode too so I suppose it's not too game breaking.
The camera could also use some more smooth movement so it doesn't abruptly jerk up and down when the character changes y position but that's just nitpicking.
Building is good, the side selection strip could use a few extra materials up and down so you see the material you're looking for.
The draw distance is tiny and looks odd, so try to increase that once you set up a lod switcher for everything.
tl;dr; Darker foilage, more AA, move the camera center from the top of the head to beside the shoulder, smooth camera, more materials to select, larger draw distance. Nice work.
