TFP Starscream

I did this drawing an hour before biology started but I didn't finish it until I went home that evening. This was all done in pencil except for Starscream's eyes. They were done in red marker. The thing on the center of his forehead and the missile attached to his arm were done with a combination of graphite pencil and red colored pencil. I wanted to try drawing Transformers characters with more than just Photoshop so I tried it out with graphite pencil because I love working with it. This is the result. I'm planning to use different mediums in the future.

Here's the image I used as reference.
