Yes, that's a cool looking bridge. Tom's new one is OK, but it's not a Tanks's Super-Hi-Res behemoth.
Yes, Mike's Pioneer bridge is indeed adequate.
As for the marsh. Yes, I've got your marsh from Tom's, but the water that's in it is just bland. ie. It's all the same color. No variation. Just doesn't look right, when used with your water.
Actually why I ask all of this, since d'ling and installing your new trees and stuff, the game has gone back from the subdued look of Magua and the like, to the original bright BTS look. No offense, I think it looks really good this way now, due to the shear quality of the trees and bases, but I need a new brush mod. And I'm grateful for you to be working on it. And yes, I can't wait to see your new boccage/hedge texture. I'm still using Magua's and it really doesn't look right with your stuff.
As for my grass mod, I using Gunnergoz's Dark Field Grass, which IMHO is the best looking grass ever. It has great elevation differentiation as well as a somewhat realistic grass look.
