Great model ruined by poorly done tilemapping. 
Thanks your constructive criticism. I'm pretty sure smoothing every sharp edge in Bastion would make it prettier.
Okay, let's stop this trolling. Quality of the textures actualy are not depending on my mapping skills, as I can do both UV and tile. The problem is in lack of dedicated texture artist, as FSK disappeared long time ago. At least I'm trying to use tiles in similar way as Oddgrim used them in Asteria, not to slapping random tiles everywhere [just like most of the tilemapped ships are done], but using specified parts of the tiles to texture individual details. I think it works fine in our current situation, when we facing lack of texture artist. At least nobody complained about mapping of the Ishtar.
Color scheme is the same as in original Bastion by Psycho. I'd like to change all purple and cyan parts to light blue, but that decision is actualy depending on project leaders.
As for the Diablo, it's actualy not tilemapped. It uses two dedicated textures baked from the tiles. I doubt if any member of the Inferno Team has enough texturing skills to do make better textures right now. We are always open for help from the outside if someone volunteers
