This is a drawing of the GF Fox. its a light weight front lines attack and scout vehicle. its got a top speed of 120 mph. its armorment is a 40 cal gas powered automatic cannon with a fire repatition of 1 sec in between rounds fired. the turrent has a 360 degree rotation, with a 75 degree incline. the cannon has a range of 3 miles and is accurate within inches between 2 to 2.5 miles. the cannon is manual fired from the cockpit. the GF Fox can hold 2 people.
I like these pictures too. These concepts are very close to what we are looking for for our RPG. It is Sci-Fi, but not TOO high-tech. This is a good concept. Try inking your art, and then erasing the pencil to give it a more crisp feel. When scanning, Scan in GREYSCALE only, and play with the levels to get the image close to BLACK and white with less GREY.
this would look sick in perspective!
