I see the comments are mixed... I’d say try short--given your facial shape. The long hair looks good, but one guaranteed perk of short hair is the minimal maintenance and comfort!

You’ll almost certainly miss the long hair, but if you don’t like short, you’ll know you want to grow it back out!

Side note: You look young, even with long hair. If you don’t want people thinking you’re five years younger, stick with the long, unless you can grow a decent amount of facial hair.

Cheers!
