I don't see how those maps are too bright, unless you're playing at night with lights off and contrast cranked up. Certainly not bad enough that this alone would warrant a change. I can see a bit of an improvement on Blade because texture looks cleaner and more uniform, but LightBeam now just looks like rock rather than snow.
I'm playing at night with low light and I think many people do. These two maps, especially IceBeam was disturbing me so I tried to solve it, that's all.
And yes, I think I need to blur the texture of IceBeam, I just decreased brightness and left it there, it needs blurring, something like in the Fryer's stream modification. Maybe I should just darken his textures.
By the way I don't care if it looks like rock instead of snow, that doesn't mean anything for me.
