I'm a complete newbie to it. Only concepts I aplied to my drawing was perspective (which is actually isometric) and shadow/lighting I took a look at your gallery, and you are good at drawing, so the only tip I may have is to play games and pay attention to the stuff in it so you can have your own cool ideas for your concept art

What bothers me is the corner on the left, I think it's too pointy : )
