First try on modeling for Dawn of War. But a hi-poly monster now, will definitely reduce the poly number before texturing, animating and importing in-game. 
Some small update:
optimization before texturing:
Weapon choice: heavy bolters, heavy flamers, las cannons, multi-melta
That's a great start!
Some small details can be just painted on textures, there is no need to model them all.
ty :) Texturing is always a hard task for me, and I still try to learn how to texture in DoW art style. I have already optimized it and reduce unnecessary polys.
