Unreal 4 Environment - Nydalinn

Update on my progress.

Added sculpted rocks to the scene, textured them in substance painter and then added snow over the top parts in Unreal engine.
Redid the water shader following this tutorial

A couple of steps in between previous post and the next screenshot.

Further adjusted the water shader and added snow on top of the wall meshes.

Added blue crystals, and took another camera angle.

Then went on and adjusted the water shader even further and added my previously sculpted ice to the scene.
Not really that happy with the water yet, so going to see if I can adjust that a bit further.

Let me know what you think about the materials as they are currently, so that I can fix them accordingly.
With or without the blue crystals? let me know guys.

Thanks for the feedback in advance.
