Looks like a good job! I always try to parkerize instead of blue if the customer will let me. It's way easier and holds up better. Just looks weird on some guns, like Win 94's and such. The only thing I'd add is when blasting, I use silicon carbide and not aluminum oxide. I've had the al. oxide mess up the finish by getting imbedded in the metal and ending up spotty. Also, oil is the enemy of parkerizing! Wear rubber gloves and don't let the slightest speck of oil get on your part or it won't finish properly.
