This is the first of a series of fundamentals questions I (hope) to ask. I am an extremely amateur artist who is working to make himself better, however I have only been drawing seriously since eighth grade (I am a senior in HS now). I am creating a game with my friends, and they wanted me to be the concept artist. While we aren't in FULL development until we go to college, we are nevertheless trying to better our skills.
So, I wanted to get a grasp on some fundamentals. Drawing weaponry and objects (like machines) required attention to detail, but before that can happen, I need to know what is at the base. Line placement and direction... anything that can help. If you can tell me anything I need, I would appreciate it! Have documentation? Please direct me there.
Thank you in advance, I sincerely hope I'm not breaking any rules!
