I really like that first character a lot, and I think you did a great job on it!

The optical character ("OPTIC" for a name suggestion?) is cool too. As far as color suggestions, pulling just a small bit of that bright blue from the eye into the uniform design would be cool as long as it's subtle. I also think that an overall scheme of some kind of neutral blueish gray would really reinforce this as well. It would convey both a military look while also playing up to the blue from the eye. This is provided that you are going to keep the same colors. Making a team with a sort of unified color scheme with just some minor variances would be cool, too.

I hope my suggestions are helpful! Thanks for sharing!
