Man, that ref. is friggin gorgeous. I was kinda tryin to get the general feel of french architecture first and foremost, and figured I could make some more messed up lookin tiles after I had the right overall shape, but that will help immensely.
As for Jad's comment, now that you mention it, the highlight on the bricks does look kinda wonkey. Ill have to fix that, although Im not really lookin forward to edditing some odd 100+ tiles... well, probably less actually, as the roof for example wont need it. Im going for a somewhat minimalistic style, largely just because there are a lot of assets I need to make for this game, and that makes it easier to keep them consistent, and prevents me from spending days on end working on one sprite (I mean, I still end up doing that sometimes, but now I can crank out the simpler stuff.)
That being said, I would still love some pointers on shading, and an edit would be greatly appreciated. Im not really tooo strong on it, as can be noted by the lighting on the bricks, and overall minimalism, so anything you could show/teach me would be awesome.
*EDIT*

That took less time then I expected. Fixed the highlights on the bricks, because after Jad mentioned it, I couldnt un-see it, and it did look pretty wrong. Now they are more consistent, with the highlights being in the top of the bricks... makes a bit more sense.
*EDIT2*
Now the windows are buggin me, Ill probably re add the bottom highlight to them.
