Nice idea, I genuinely think that there are some folk who really do give good/great feedback, and you can tell too (well I can).
Three names I can recommend are: @
Genocide @
King Keith and Vulgar (I'm not sure whether he has an account on here yet). All of them have given me feedback to help me, whether its my flow, concepts or whatever, they know wassup.
But I'm down for that, I'm open to learn new things.
