sketching

[snake85027]

I know this might sound sad but I am trying to get better at sketching, I am interested in futuristic industrial design. Like the bots in deus ex or splinter cell or really anything cyber punk. I have been with a game mod for about a year and we are starting up again and I want to be in the creative design process and my first model design is a hand held augmented spy bot, that hovers and spies on enemies. Ill post some drawing that I did and put myself out there and prepare for the worst.
