I have to agree about that many garbage gets overrewarded while good content is ignored. Also that spend 10h or 20h in a drawing to post here, and don't get decent rewards is not encouraging. But that applies to things specially drew to post in Hive, not the comissioned work, or drawings made for fun/practicing. They probably deserve more rewards, but don't portray the matter like you are drawing all of them for Hive.
You should consider that if everybody recycles the same content again and again, readers get bored and don't reward it, also the place becomes boring so lose value, and that doesn't bring more users and investors to Hive.
