Enough air holes for a Versi?

[Jimi Thing]

So I had decided on purchasing this

but after doing some thinking and building some smaller enclosures, I decided to build one out of a 5.5 gallon tank instead.
My question is, in your opinion does it look to have enough holes drilled for ventilation?
Also, I know this is a pretty popular style but what are you using to keep the enclosure closed?

Thanks for any advice!

To keep my enclosures closed I use 3m command hooks one on the top and one on the door and use a hair tie too hook them together

Hmm, that's a pretty cool yet simple idea. It kinda pisses me off how I walked the floor at home depot looking for something and it could be done with something as easy as that lol.
Thanks.
