Good stuff my man, loved the video. Make good use of modularity for the bridge and towers, and series of tiling textures for the cave and what not. Looking forward to this beauty!
Learning stuff like building in a modular fashion, efficient use of textures by tiling/blending, scene layout, whiteboxing and composition, lighting and researching architecture to name a few.
It is just that. I'm not sure how else to turn the square modular asset into a tunnel; if I have the sections meet at a ninety degree angle it creates a lot of interpenetration.
