My first Weekly Challenge entry as well as my first submission. It was fun working with the challenge's constraints. I look forward to participating in future challenges!
Welcome to PixelJoint! This is a pretty awesome first submission - I love how you managed to give the T-Rex such a cool quizzical expression. Even without the ? bubble I'd recognize its confusion.

Thanks for the warm welcome, guys!
@Quiara: Thank you! Thinking about it now, the question bubble wasn't really needed.
