Cliffs have minor errors but nothing too bad.
Your path style reminds me of Zodiac...I like it a bit more calmed. Grass on grass looks ok on the bottom but you used too many of the small bits. I like the way you group your swamps, you seem to use too many blocking tiles for the detail. However I think it looks ok.
You need to work on your water styling. It looks like one big tile error. Trees are fine.
Overall I'd say 5/10, which is pretty ok.
