Is this a good skin routine?

Sounds great to me. It's essential to wash your face twice a day to remove dirt and dead skin particles, and you clearly do that, and it is also essential to moisturize. The weekly facial masques and scrubs are pretty good, but you may want to cut them down to 1 masque and 1 scrub per week because to many scrubs and masques could cause a bit of irritation over time.
