Hello. I want to be a concept artist in zbrush, subd and cad, do 3d concepts, some stuff like ACMS, Bulgarov, Mike Nash etc. and would like to ask for advice. What do I need to study first? If I say that I have 400 days to learn this profession. My job at the moment is a 3d prop artist, I know sabd texturing. A 3d concept artist needs a 2d base? Can you recommend courses or books for me? Alex Senekal's courses? I want to do sci-fi and characters in general like Mike Nash did.
