Well, the size they're uploaded in the big form is the size the customer gets, and some folks like to get a big version. They're paying more than you'd typically pay for an icon, so, I try to make it nice and give them the file size I work at :) Granted, they're not as detailed as say a mini painting or a badge would be, but it works out!
