Freestyle - Roofs (3D)

I've been doing a bit more 3D lately, using a picture I did some years ago, that was used for a contest on Polycount.
I used a specular shader this time as it's closer to my 2D technique. The unwrap was faster as I used seams, instead of an auto unwrap, but painting the normal map was again pretty long.

Anyway I learned more stuff like sculpting and unwrapping straight before duplicating and tweaking shapes, alpha textures, reflections on transparent materials, depth related color (for the water), z-axis fog, giving several unwraps for one objects, ... but didn't manage to have a good refraction in the pool, and I'm interested to see how I can generate more indirect lighting, instead of adding multiple light sources to fake them, which made my PC suffer.

I'll check that maybe later but it's pretty crazy how much more time I needed to make this, compared to the picture ^^'
