Wasn't that the one by X-tender? Where all the textures looked so dusty?
I'm gonna post you some feedback later today, just a short "teaser" for now:
1) The way they are now, I wouldn't take your cs_mario_b2 waypoints into my waypoint folder - yet.
2) However, they show VERY MUCH potential and don't lack in elemental things. It's just some details and much stuff that can't be expected from someone who doesn't have much experience so far. (The map wasn't exactly easy, btw. But a great example.) I'll show you what I mean in full detail a bit later.
