Congrats on you new darkroom setup, looks like you are off to a good start. Nice image btw. As far as the odor of selenium toner just make sure you have good ventilation, should be to hard since since the toning is done in the light. I find that generally my prints look better selenium toned, increased dmax, elimination of the slight olive tinge that some papers have, etc. I keep an untoned print in a tray of water so that I can gauge the amount of toning and not overdue it. Don't want the print to get to purple.
