The banana was being a real pain with ramp shaders too, probably because I only modelled half of it and applied a mirrored subdiv proxy. I wasn't too worried about modelling accuracy (I did all the modelling in about 2 hours) but I focused on lighting and shading in this one, using a three-lamp setup with a different color for each lamp for a sort of warm glow, and actually have the yellow lamp projecting a light fog. It's kinda hard to see with the purple though, I probably should have upped the density a bit.
Thanks for the comments, everyone.
