Oh, at first I thought you said you WERE a cat...
...Then I realized that was your name, not your status. xD
But anyways, you have some nice stuff in your gallery. Especially your most recent layout, "91 Chamber". It is a very nice technical drawing.
Anyways, good luck! I hope you do well in your profession. Who knows, since I am going into a Concept Art program in almost a year, (once I finish my "Pre-Animation & Illustration" program) we might even work together!
Well, it might seem like something in the realm of fantasy, but all of those really good Concept Artists are real people, like you and I, with 2 arms and legs. They started from the bottom, so if you have the passion, and REALLY want to do it, anyone can get into the Concept Art industry. The only reason why everyone is not a concept artist already, is that you have to devote your life to it, something that most people are not willing to do.
...But I suppose you already figured this out by now, choosing to go into graphic design. And if not, perhaps consider it...who knows what may happen in time.
