Hey bud! Good to see you! :) Looks like you forgot to use the #introduceyourself tag, but besides that.. A good introduction!
It may be a bit slow at first, but.. I think if you take it seriously and regularly post your artwork and ideas that you'll really start to enjoy it over here! And heck.. You may not even use Facebook that much anymore if you truly start to realize how much potential there is here.
I still post on Facebook, but don't spend much time over there anymore..
Hopefully in time many more continue the mass exodus, heh. You're still pretty early.
Anyways. Glad to see you on here and don't forget to ask if you have any questions, I'll do my best to help.
