Is 16 pages enough to tell complete selfcontained one shot short story?

Hello

Ive written 16 page comics that are self contained, but i have that nagging feeling that 16 pages isnt big enough and it is too cramped. but i enjoyed writing them, so because of the ffeeeling i tried to write longer ones, but it was down hill and ive became rusted on 16 page stories.

Do you have any advice for my situation?

Thank you for reading.

Cheers.
