TFP- Sketch Dump

Sketch dump, from various sketchbooks and notebooks that I've done recently, but have no real desire or gumption to finish. I usually use it as a way of practicing and just keeping the drawing arm strong, so a LOT of stuff I do never really makes it onto the internet. I should make a conscious effort to try and post more art, but given classes and the painting schedule, that kind of takes some priority for the time being.

Anyway, Knock Out, Breakdown, Skywarp, Thundercracker and Jetstorm belong to Hasbro, Art belongs to me.

Which is your favorite?
