Added a simple ground texture, “colored” the airplane with a “toon shader”, and turned on “Freestyle” in the render section (which is how the pencil outline was made (I used .500 thickness, “absolute”.)) 
Still not sure how to control the lines better >.>, tried to edit that half line in Photoshop, but I couldn’t match the half pixel that Freestyle did… I guess that’s something to keep in mind next time xD
