A little story behind this: I wanted to make an Animated Cy-Kill (revamp of my old idea), using Oil Slick's Cybertronian mode. However, no model sheet of him was ever leaked, so I had to go to screencaps for help... which didn't provide all that much help in the long run. So, I pieced together what I could gather from them and mode a model of my own. People are free to use this for drawing reference, but I can't say it's 100% accurate. Tread detailing for example is uneven. So, if you happen to use this as a reference, please refer to the Transwarped episode for more details on his design. In the attachments I'll include screencaps I took which is what I used when drawing this.
nice artwork, very impressive... are you going to turn it into anything, i.e. a transformer toy or something? great post!
