A crimson is simply a hypo miami. A miami has more of a gray base color instead of orange. Honestly, I think your may develop more yellow and orange as it gets older. Yours has a lot of yellow showing in the base color near the head. It may very well be a hypo, but as was said before, there is no way to know for certain without breeding trials. THEN...you may have to breed it with at least 3 different hypos before possibly finding one that is compatible with yours.
I personally would just keep calling it a normal until I knew for certain...
