Have I missed my chance?

I looked at some really good creators' work on Spore and I noticed how much they have improved, while I have stayed the same. A great creator (Antic76) has commented on some of my work (probably to stop my nagging) but I still haven't got any better! How did these creators get so big? I think nobody plays my missions because my first ones were crap, so I've earned myself a bad reputation. Does anyone have any ideas on how to get recognition?
