On the carpathian map, this is the problem with changing out textures to something completely different: the walls are rock. They aren't stone walls with masonry or bricks. Nothing but rock really makes sense there. It just looks weird. If the walls were flat, it MIGHT make sense, but they're not. They're very organic. Even if they were flat, that texture would look out of place in other maps where the rock texture was used as, well, rock.
The S + S grass, aside from being very bright and washed out, does not tile all that well. If you look at the distant ground texture, you see almost a checker pattern of alternating light and dark lighter areas. That particular grass texture is actually from a photograph of real grass, so saying "real grass doesn't look like that" doesn't make sense, because, well, yes it does. There are lots of different grass textures. Some are deep and green, some are lighter and green. Some have a mix of dead and live grass. Some have rocks. I want to keep the variety that's there so mappers can choose the texture that fits their theme. Replacing all the grass with the same texture like the S+S pack is just... bland. Every map starts to look the same.
On the renoir screenshot, that texture is scaled up larger than the rest. That is going to be the case regardless of the texture used. Take a look with a different texture pack.
Hopefully this weekend I'll have some time to review some of these textures and make adjustments based on feedback.
UnRateD: Not to defend my textures, as I know some certainly need the quality improved, but that's the biggest problem I have with most of the texture packs. Some of the textures are OK, while others have glaring issues and just look bad to me. I guess people get used to them and start to think they look good after a while. It's just weird when people post screenshots of, what I think are, really bad textures and say something like "See how much better these look than the official textures?! You need to make the official textures look better!" I'm really not sure how to react to that.
