I also created a program to convert images into a texture which contains information about its width, height and depth, as well as create mipmaps. It doesn't at the moment support compression, I'm starting to think maybe I should use dds files since I recently found out that they can be used with OpenGL (if you have a DirectX header). For now though, it works, and so I'll keep using my own format.

I've also been modifying my bloom algorithm, this one seems to work a lot better with my scene. I've noticed my messing around also gives a great refraction effect (see the red area).

As you can see I've added doorways now, and well as roofs (although some are still not quite complete roofs yet). There is a new terrain being work on, that will hopefully be better for area Totus village is in (between two mountain ranges, with a forest to the south and plains to the north).

I'm currently decided what to do with the walls, its hard to tell from the original SNES graphics what they were trying to do with the walls. On the one hand they appear to be supported by beams, on the other those shadows on the beams could just the be the wall on the upper half. I've began working on a tool that takes the COLLADA file and converts it to my geometry format, as well as some geometry optimisations through Tootle.
