That is good for MS Paint. Your talent's being wasted. I'd like to see what you could do with a real program, like Photoshop.
use this instead then - http://www.splashup.com/ not as fully featured as photoshop, but it is infinitely better than paint, totally free, and runs in your browser
or try Gimp, it's free. There are more options than just Paint. Your skills are being restricted by a crappy program.
i have gimp and one thing, until i learn how to fully use any program, i dont completely rely on it. im still learning how to use gimp
three more colors Armada Ultra Magnus Cybertron Armada Optimus Prime Armada Nemesis Prime Toy Version all six (smaller)
now you all can color prime as well i created this blank, just keep the shade of the color (lightest darkest and middle) with the shade of grey (white dark grey grey) then it will be fine you can also change the color of the background
