CHMS is a KO.
I can't tell from your pic which it is. I'm seeing things both for and against it.
It also doesn't help that the official Henkei Skywarp had a fair share of issues (though not as bad as poor TC). So the fact that the cannon/s is/are loose is also a plus in your favour.
A clearer pic is needed, especially of the head. The details should be sharp, and the eyes precise, not googly and a mismatch to the area.
Yours does have the black wrist overspray common to a lot of the CHMS KOs.
Post a close-up of the head and we'll be able to tell for sure.
As is, I'm leaning towards the KO, but it's by no means definite. I'm 51/49 split on it at this stage.
