This model took me about 7 to 9 hours to create.
It has 3 textures - diffuse, normal and specular, all made in GIMP. Works very well in realtime renderers.
Whole mesh is manifold and consists of 1662 triangles.
This one should only be for learning purposes, but who knows... ;-)
It is going to be used for our game project the Eleventh, which you can find here: http://www.the-eleventh.com
