Mouth/Lower Lip

[dpcsquid]

Hey everyone, hope you guys can help me out. Here's my baby cornuta and it appears that his lower jaw is sticking out very slightly (you can see a contrast between his chin and his "lower lip", which is lighter color). Is this normal? He's eating fine and doing everything else fine, and this is a fairly new development. Because I've never raised one from so tiny (I've had him a few months now) I just wanted some imput.

Thanks!
