Awesome looking textures Dimitriov! However, I have a suggestion: how about creating custom roofing textures to match your high-res building textures? At the mo it looks really odd to have high-res buildings with crappy low-res roofing applied, so I think in the interest of continuity it would be a good idea to supply roofs with matching texture quality.
Apologies! Just the first thing my 'designer eyes' picked up, lol! Great work otherwise! :thumbup:
