Yes, I'm going to be a hypocritical bastard and post this in the main forum for the sake of more views. I hate myself.
Anyway, I tried my hand at outside levels for the first time today. It isn't finished, but I'm posting a small screen here for some tips and criticisms. It's certainly nothing special, and I borrowed liberally from existing levels, but for a first try, it ain't too shabby. Better than some levels I've seen here, anyway.
Fire away.
