This is really something, I'd love to know how you started when it comes to concept art. I'm aspiring to be able to draw like this one day but have no idea where to start, are you a competent drawer pen on paper? I am not so much, and would guess that is where I need to start. Sorry for the long comment, just really like your work.
Hey. Thanks. No problem. I`m glad you like my work. It`s been a while since I used pen and paper. Now I use only the Wacom tablet and Photoshop since it`s easier for a lazy guy like me (no pencil sharpening and stuff like that). Whichever medium you use, it`s good to start with learning the fundamentals: perspective, light and shadow, anatomy... There are a lot of good video tutorials out there. You can even find some great ones on youtube. Books are also very useful. Most important - it`s a good thing to practice every day by drawing stuff in a sketchbook. Hope that helps.
