It's up to you to decide if it's worth trying-- if it is, you're a poet; if it isn't, you're not.
In this case, I agree that a new version is called for-- but I think it's certainly a good idea worth playing with some more-- by no means, however, can you 'leave it alone until I acquire the sufficient skills' because the only way you'll develop those skills is by writing. Don't save your 'good ideas' till last; you'll never get there. Write about what grabs you now now.
If you really want to work on your stuff, I'd suggest you participate somewhere like
EVERYPOET. They can be-- will be-- cruel as well as honest, but they will help you if you stick with it. Be sure you look through the site thoroughly and read all the guidelines before you post a poem-- they can verbally slice, dice and marinade a poet who posts at too high a level!
