The stance of the lighter blue character is a bit odd. I'd have him standing at an angle. I would also suggest you change the floor color, it is too vibrant. Maybe a pasty brown of some sort. As for the eye (i think that is an eye) of the darker blue stick, i think you had a great idea for having that lens flare in there. My advice for you is to create that in a different way.
Here's a pivot animation I made that involved lens flares.
Usually they go side to side, and not up and down, but for the eye i suggest both, as you have already done. Just use a different stick, like a simple line. It ought to do the trick.
The mouth (i think its a mouth) is pretty odd, it takes your view off other things because you try and decipher what it is. Try to make a more mouth like stick
If that's an eye, then put the other one there lol.
Due to there not being any movements, there isn't much to cnc. Good luck
