I'm a bit maniacal in some of my collecting but never in my wildest imaginations could I imagine having that many Dark Age figures. So, a well deserved Wow!
(My greatest mania must be my Old West/Pony Wars collection that all in is over 5,000 figures but that includes wagons, animals, dead, civilians, etc. Truly massive to an insane degree. But if I'm having fun that is the whole point.)
As to painting quality, being a 'servicable' painter myself, no need to apologize. As you say, some here are very talented (and some of them are professional miniatures painters and others are well trained artists and some are just skilled amateurs) and the rest of us paint for our own pleasure and to have figures ready to game.
And that is the critical rub, your figures are painted and on textured bases ready to play - and designed for playing. A lot of those wonderfully painted figures spend the majority of their life on display and not on the table top. Nothing wrong with that, of course, but I prefer figures painted to play with.
