Nice bust and the painting on this one is astounding. Might be the best application of red I have ever seen, and the metallics... . One thing. I believe as an Optio, his crest should run front to back, the Centurions having the crest that ran side to side. Easy correction should you choose to do so, or leave him as is and call him a Centurion.
. This is however the first time that I have seen a Roman depicted as wearing his Flare (decorations) on a harness over Lorica, which may be the reason those Centurions (who would likely have amassed a few decorations in their time) wore something else, it might have been a bit too bulky?
The correct way to display flare:
