I like the hue of the toned version much better (I dislike the green cast of most papers). However, the open shadows in the untoned image are much more pleasing, especially the shaded part of the face. Selenium toning can dump shadow values quickly and often disappointingly along with increasing Dmax. This, as Matt points out, could be a scanning artifact. Still, it's a good idea to print a little lighter with important shadows if you plan on toning. I'll often make several versions of a print and discard the ones that tone to darkly (after drying, of course).
@OP,
Keep in mind the "1+7 for 10 minutes" is going to be different in freshly-mixed toner than in toner that has been used for a few prints. Try it: tone a print in your freshly-mixed toner for x amount of time and reserve an identical one. Tone a bunch more prints and then tone the duplicate of the first print for the same time. The results will be significantly different.
I find it better to arrive at a toning time by observing closely till I get the tone change I want and then toning the other identical prints immediately following the first. Then I move to the next print, determine a toning time that gives me the tone change I want and tone the duplicates of that print immediately. My point is that time and dilution toning is simply not repeatable; you'll get different results as the toner gets used and loses activity.
Best,
Doremus
