I think that I am trying to convey that your next "project" should be some basic drawing. Like draw some fruit in a bowl, go buy a big ass sketchbook and fill that fuckier with still likfes of everything you see.
Just gesture drawings with some shading, Then buy another sketchbook, and do the same exact thing, but this tiome, refine it a bit more. Dont stiop till youve filled the book. Draw for three hours a day. Bust your ass, and then....when you can grasp shading, balance, composition, symetry, line quality....then maybe you should try a concept. One.
Re do that same one twenty times until you get it right.
