Good to see you work on something, but I got some tips.
Graveyard is really cheap, its just copy paste you should change that, put some more time in that.
The textures inside aint very well, they go from a texture to texture without anything in between which makes it a bit weird, put something in between there.
Tips on how to work:
First build a skeleton or how ever you wonna name it, put big boxes where you want buildings and objects and then test the map, thats just for the gameplay. Then replace the boxes with models and give buildings a shape, add some basic textures and play it again. Add final textures and decorate the whole world, add details that don't take a lot of memory but just by texturing or something.
take those steps next time you start, don't focus on the windows and such and textures in the begin, just stick with basic to see if it plays well, because thats where it is all about in the first place. GL
