thanks and well, i've never been to any art college D: i'm self-taught. and I think graphic design is a bit more focused on layout, vector graphics and stuff like that, if you want to do such concepts go with industrial design or concept design for entertainment.
Very beautiful design with that ship. I just cannot understand how do you do something like that in 1,5 h. Did you sketch it on paper or on computer at first? And another question, what program do you use?
