It's great that you don't alias too much because a lot of the details could easily have been blended into nothing. This piece, and the other ones with planes, are pretty similar to a style used by a lot of VGA pixel artists. You've definately got a good idea of where one pixel lines make all the difference too.
You have a command of pixel art. You are one of the most talented artists on this siteOK enough kissing ass (jk it's true). Anyway I love your backgrounds, especially the clouds--they're amazing. I love the plane design too. It's all sveet. Favorites!!
