I think both galleries has it's own sets of pros and cons. Traditional artists would argue that Renderosity caters more to 3D (have heard that a number of times). I have an account in both, however, I get a lot more commissions through DA than here. One thing that frustrates me though is the fact that most would turn up their noses once they hear the P word uttered. If it is indeed an easy tool and people uses "pre-made" figures to create an image then there wouldn't be a single crappy poser image out there right? We all have to start somewhere...it took me months to learn my way around it and it was only because of the people that gave me feedbacks and suggestions on how I can improve it. Instead of being all high and mighty about how big ones software is - why not help those that you think needs their craft improving? Afterall isn't that what a "community" is supposed to be?
