This would be a lot more fun if it lost the time limit. Make it's duration indefinite, but requires concentration. It already differs from the PnP version, so a further change wouldn't be out of order.
Prestidigitation (Wizard cantrip, advantage on Performance and Slight of Hand) and Druidcraft (Druid cantrip, advantage on Nature, Handle Animal and Survival) could be implemented in the same way.
[I'm assuming druids are coming soon]
