I doubt you'll find many here who are trying to find literary agents. You should probably have posted this in the Help and Support thread. :3 I can redirect it there, if you are serious about trying to find an agent to get yourself published.
As for a critique group:
khi-critique-center-2-0 You could join this and hope there are writers out there who will ask for their stories to be critiqued.
I think there are threads already to discuss suggestions, or get an outside perspective. You just need to look here:
inspire-uninspired-thread or
khis-fictitious-tips
If these aren't what you're looking for, then please PM me about it.
Don't hesitate to ask me anything. I'll help you in any way that I can!
