split filtering? never heard of it. i've worked with magenta filters before, and loved the results- that's what i was gonna suggest to bump the contrast. you could also go with a slower developer, as i recall. no kidding, that was so long ago i forgot alot of the techniques.
btw- i wanted to say all the way back at the beginning of the thread that you do not suck. in fact, i'm not blowin' sunshine up your *ss, but i really do tend to pay close attention to your critiques because i think you really know what you're talking about. i'd say the same about your photos, this one included.
