For a 1st attempt they're pretty good. You've got a good range of tones and print contrast seems OK. Well done. Temp. control can be a bit of a pain but if you're serious about this printing lark then you could invest in a Nova slot processor which solve all the problems associated with temp. control chemical storage and space in one go. You could also look out for some used dish-warmers (the new ones seem to be ridiculously expensive for some reason) but having used both, I'd settle for the Nova units any time. Can't comment on using a stronger dilution of dev as I've never really had a problem keeping my chemistry at the right temp!
