Sounds like it is going well! Good job!
Side Story:
My first ball python I would feed in a cardboard box outside of her enclosure. Over time she associated my hands with feeding time and would take a few crazed strikes at me whenever I reached in to perform husbandry. It is not a big deal when they are small, but, as they get older-those half-hearted strikes become full on feeding bites (and getting bitten and then have the snake 'constrict' and twist the teeth in your skin-is no fun for anyone).
Eventually I just started leaving the rodent in the room for a few minutes to 'scent it' in advance and I would see her head stick out and I would know where to reach in with forceps and dangle the prey item. Sometimes I would use a plate on top of the substrate beneath the rodent to make sure she did not get a mouthful of 'dirt' while eating.
With a much larger collection now-all of my ball pythons eat within their enclosures and have associated the scent of rodents (not my hands) as the indicator of feeding time.
