Hey if you have time to answer, I'd really like to know your technique on rendering buildings. As it is something I have quite a bit of trouble doing. I'd really like to know, as this is a beautiful homage to the concept artists at Ubi.
Hey there. Well to be fair everyone kind of develops his / her own technique. I usually make a line sketch and then paint. Sometimes if the time pressures are high, some people use textures to speed up the process. I think the best way is to just do some single-building studies and figure out your own comfortable way of painting them. After that it's just a matter of multiplying the technique while keeping the whole image in check.
