Question about Instagram?

[Sophie]

Hi guys.
I feel like an idiot.
I have had an instagram account for ages now, but only started using it properly recently. I post what I think are fun, quality images. I am a model, so I often post shots from shoots and behind the scenes pics too.
What I don't understand is why I only have 51 followers?!
There are so many accounts that only have 1 photo that is some scam on how to get more followers with some rubbish website, and yet they have like 900 followers?!
It's really getting on my nerves.
Can anyone give me any pointers on how to get more followers pleeeeease?
Thank you!
