Ok, I tried both of your fields, they look awesome. Now in further details:
- On itmin1, it looks like there's a minor issue regarding the table top. The way it's cut and overlaid has two small problems: it leaves a small transparent gap with the underlying layer on some parts, while on other parts it overlays with aliasing. I invite you to check if my method of separating layers (directly in Blender, for the most part) would remedy this problem (since I didn't have problems of the sort on my scene).
- On itmin2, I couldn't get behind the chairs because the old man and his dog are blocking the way. So I couldn't verify the overlay, but I don't think it matters (after all, if nobody's going to be in that area, who cares?). Also, the game engine is cutting the layers is such a way that it makes a small dent in your image (down left area), but as we discussed with Aali, it can't really be helped. On another note, I would suggest you consider scaling down the tea pot (probably make it half the size), because it looks humongous with respect to the other objects of the scene.
And for extra information (a detail that caught my eye, I don't know if you noticed it): would you feel like modelling the Girl's room in the Honeybee Inn (onna_2)? Because the scene features exactly the same chairs as in itmin2
Overall, great job and thanks for sharing
