These new trees is definitively an update to the better. I like it. The uniform look of trees of the same type clustered together is no problem either.
The green mush is not big problem - but if its suppose to symbolize shield-grasslands, I would prefer any markings at the center of the grassland-tile instead.
I definitely agree to that. Nice work.Lifting the land off the water made a huge difference in appearence, it now looks a lot more proper.
They look too much like planted crops to me, and less like regular plains. Actually, I would prefer the "darky orangy look that Civ3 currently has", compared to this.The plains, I may have gone overboard with that, but in my opinion, its better than the darky orangy look that Civ3 currently has.
Why not try to change the look of irrigated tiles as well. At present they look horrible. They should make the irrigation-canals more thin & regular: so that it looks obviously manmade. Also some very slightly protruding crops between the thin canals.
The simplest (and best) solution would be that all the plantable terrain-types: grasslands, plains, hills, deserts and tundra would have its own uniquely coloured irrigated crop.
