I'm part of another forum called GameRenders which I've been a part of for over two years. Basically it's just a bunch of people posting their renders. I've been rendering for over two years now and the best way, to do it is using the pen tool, in other words paths. This method is time-consuming but produces the best quality render. If you want more details PM me, and I can tell you where to find help, or I can always help you. =)
