Honestly,

I find it tough.

In pics 2 and 3 he has that place where the dark bleeds into the orange, the reduced patterning and banding.

None are great examples of the morph, but it may be a low grade enchi that is just dark enough to question it.

Also where you have flames, the flaming has a burgundy tint coming up from teh belly.

Really a tough one.

Here is one of mine as a comparison.
