Once the loose sketch is done, we draw an over-lay to clean up. This vehicle is in perspective, so we made some basic construction lines to aid in the
drawing process. You can see some construction lines near the front of the vehicle. Since this vehicle is based off of a tiger, we made the design similar
to a cat's face. Also think about composition. Notice how all the major lines lead the eye in a certain direction. For the vehicle, the "face" has a triangle
shape pointing down, while the "mouth" has a triangle shape pointing up. This will give the vehicle some focus. Same goes for the character's guns.
Each gun points to the character next to them; leading the eye to flow.
