The terrain and houses are 99% as in real life. The model is low poly(just under 14k) with decent detail. the texturing is basic but quite nice. I have submitted the .blend the blendswap and OGA (Open Game Art)
There is an even easier way in GIMP to have good quality 1080p renders in JPEG format. When exporting to JPEG in Gimp, set quality slider to 90 and change subsampling to ‘1x1, 1x1, 1x1 (best quality)’. Doing so you can cram a 2.5 MB 1080p PNG into a great quality JPEG for a measly 330 KB.
