Well it must be me because I have a record for purchasing custom made items and either never getting them, long delivery times and/or no communication. For example:

Mermaid tail by Adam Martin: 8+ years STILL waiting, LOL
Indiana Jones fedora: 2 hats ordered and paid for: 7 years. No communication or updates yet he will respond if you place a new, higher priced order.
Jack Sparrow pistol: 3 years... more my fault as I am trying to get a sideplate made which is now 18 months
Gandalf custom costume: 8 months. Sporadic communication.

Not a great track record. 20 months is nothing compared to others but I am getting a bit concerned.
