@cardvillain thank you for the feedback! I always use some type of stains/scratches to the roofs but I'll make them more prominent in the coming model, and also add some realism to walls, as you said. In fact, I'm trying to make windows look more realistic, and also so that they light up with curtains and stuff at night (like in most @Macwelshman 's assets), though I haven't quite figured out the technique yet. Thanks again.

You're doing a really good job -- 1 small suggestion, when creating the roofs and sides of the building, try to give them a realistic worn textured look -- with this particular asset you have some natural shading, but go next level and add a worn type of texture.. My suggestion is look at the assets from Smiles on the workshop, he gives his buildings a nice worn realistic look that really adds to the realism of the game. It would take what you're doing to another level. Great job, look forward to seeing what else you come up with.

@chr.is thanks man!

Impressive work and there are not so many palaces on Workshop!
