Hate to say this but I preferred the first ones!

comments:
- the grid colour of 'stable_upstairs-day-grid' is very offensive, to my eyes. perhaps use a different colour, or black?
- the light effect on 'stable-day-light-no-grid-.jpg' looks odd because there is too much green in your 'sunlight' overlay layer. Ditto the oval light effect in the office. Your best bet is probably just to use a very pale orange colour with NO green in it for this effect.
- the wooden floor of the office in the first map was MUCH better than the wood plank floor texture you are using above. You should go back to the original floor texture, and just desaturate that layer (I see you use GIMP: go to the layer with the floor texture; menu>COLOURS>BRIGHTNESS/SATURATION opens a dialogue box; reduce saturation by 60% and if necessary make the hue a little greener and less orange). Also do this with the desk - its just too red.

I really like your upstairs layout and haybales.
