Thanks for your reply, actually it is my fault not to talk about the sites traffic.Site has dmoz listing and pr3,and also listed in some resources pages.But I can't say that it has good traffic cause i couldn't find time to develop it in last five months so it stays same from that time,and also that is the cause that i want to sell it.
However,I think it can be good starting point for a new designer,the portfolio sites and the photoshop files can teach some tricky points,can be helpfull and nothing more than that.
It needs a little work to go I think...
