Sketches 3D model!

We were first given the task as a artist to create a model and show off our style/what we can do in under a week. At first I was thinking to do something cute and pink because that's what really interests me and I feel like is a strong point when creating ideas, but then I thought with a class full of boys the chances of them doing something cute and cuddly within the game, and want me as a strong artist on there team would be low and i should challenge my self and see what I can do, I've decided to do a steam punk style tank. I chose to do a tank because I thought they were very manly, and often a lot of boys model tanks, and I have seen it before in class, but seen girl do one. Tanks have never interested me and I don't really like them but I thought it was a good idea to go out of my comfort zone and try something new, and see what i can do my self, without something being cute. I want this model to be quite manly, but it wont be any normal type of tank, it will have a twist to it, With one giant belt in the middle and two giant wheels side by side, and at the back another two little wheels with giant nails sticking out. It would be remote controlled since no man could ever get inside and see from the outside, but I liked the idea enough to draw.

I got some of the ideas from-

These drawings and Lego model gave me inspiration for the sketches.
