Ok, thank you Zoggles. Made some minor changes that you pointed out, can't believe how sloppy I was with the shadowing of the plants and some of the highlights on the house and stairs. I mean I did the right stuff but as you said I need to be more consistent since I didn't do it to all of the areas/pieces.
I also adjusted the base of the building like you showed in your edit and did the same to the upper ledge to correspond correctly to the lower part. The problem I can see now is that the pieces of wall between the door and the windows is now asymetrical, I tried to enlarge (enlongen) the part to the right of the door (since I adjusted the entire building on that side) but then the window part didn't turn out right instead. I then adjusted that aswell but then I was back at the first problem again (before your edit) only the house was now a bit longer. I erased all of that, what am I missing here?
Also as for the tiling, your tiles do look better and since I'm out of time for the moment I didn't update those yet. Although I did put a little sun in there just to show how I want the light to fall, from the upper left side of the image. Shouldn't the light actually hit the way I tried to pixel? That is the crack in between them beeing lit on the left side and shadowed on the right side which is crammed next to another piece of brick?
Anyway, will play around with the tiling when I find more time, probably tomorrow. Thank you very much for your input so far.
