[Portfolio Level Design] Fantasy RPG map

I’m working on my portfolio and learn UE4 with a Fantasy RPG map. I want to release in some few days, but you will be only able to walk around and seek some treasures.
I focus on level design, so no AI, animation, fighting or gameplay elements are implemented. Just imagine a Skyrim gameplay. I have only 3 1/2 months experience with UE4
and want be experienced first in level design.

The yellow number is the fps, my systems is Windows 7 64bit, @1080p, Intel i7 3770K @4GHZ, 32GB RAM and GTX970. My aim is to devolop for games, so fps are important.

I did not make the assets only the level design. The sources I used:
-InfinityBlade from Epic
-some content from the free examples from Epic
-Grass mesh from OliverMH www.blendswap.com/user/OliverMH
-Low Poly Foliage Forest Pack from Dokyo
-some Textures from www.gametextures.com
-Tropical Plants from www.3dmodels-textures.com/store/3dmodels/Vegetation/Tropical

Feedback is welcome!
