The nose bump isn't as noticeable on your Jaxon cowl. On some of the others i've seen it sticks out like a sore thumb. I don't know why he didn't fix the mould before casting them.Jaxon on the top and OT on the bottom for your reference if you just wanna compare
It's still hard to beat the OT version though. That's pretty close to perfect.
Maybe INART will hire him for their Nolan Batman line.
