Thank you Magi, your comments are appreciated, to be honest I had no idea of how to improve it, so your suggestions were much needed.
I've made a small video update mostly featuring lighting, I haven't used the mesh painter greatly in it so the flora variety is lacking and I haven't changed the terrain either. Mostly I want opinions on the lighting and suggestions on how not to make the shadows freak the hell out (should hopefully be clear on the video)
The screenshots were made after my 80 minute wait for the video to upload and feature more of Magi's suggestions.
