I'm glad RJ's cards are starting pop up, and Darrin Pepe's also. Two of the best new artists and they (along with Crosby, Chalker, Finneral, Hamer, Labas, Gomez, Paul Adam, Jeff Miracola and others) proved a boon to the improved quality.
Once those guys' cards start popping up more you'll see a marked upswing in the overall quality. Somehow the small number of lower quality sketches seemingly all got pulled while the 2000+ that the guys above did are few and far between! The 100+ creator sketch cards have also been pretty quiet out there, save for the 50 Ed Repka did.
