Well done. The paddy fields and houses look very realistic. Not sure about the green mat and the plants on a frame, but seems like a pragmatic solution.
The "plant mat" can be easily textured by taking the plants off the frame and then covering it with D.I.Y filler mixed with brown paint, leaving the "pegs" uncovered. Apply sand, then when dry, drybrush to highlight it. When finished, put the plants back onto their pegs et voila!
