It has been a little over a year since I started doing digital art - vector illustration and digital paintings. I have come to a point, where I am resonably confident that I can provide this as a service. This brings me to ponder at where I should be placing my portfolio, in order to advertise the service? Should I do it at deviantART (or similar sites) or on my own personal site. At the moment, I have them in both deviantART and my personal site, but they are pretty rudimentary and I was wondering where I should be focusing. Any suggestions?
