Not entirely convinced about this:
1) I don't know what you did with the swap but you practically turned it into a lake, which is worse than before.
The swamp is and was fine, leave it be. Right now it looks completely retarded having hedges in the middle of a lake.
2) The *new* fields really don't blend in with the rest
The stuff you put on (haystacks, roof, very little field splines) also don't really make sense
You just put grass when the entire surrounding area has a completely different tiling to it, etc.
3) The swamp that you dried still has water splashing etc. Looks bad, you need to remove the water source and fix heightmapping.
Overall imo this is a step back from the original, there was nothing wrong with the swamps. Relic maps are high quality enough that I don't think anyone should be going in and making significant changes to the map's layout. No offense but this is certainly not something that should be done by someone with very little mapping experience. You can easily notice the difference in quality and it gives the map a negative feel for me personally.
The added player, preview image, loading screen and the sectors are fine and more than enough to make this map worth an occasional game. Good job on that, I would recommend just sticking to that.
