slr – Potential causes to bad quality of this 35mm film results

today I got the scans of my Lomography 400 roll, as you can see the quality of these is quite terrible. While I think it’s not a lab error but it’s how I handled this roll, I’m not quite sure about what might cause this. I stored this film on my refrigerator (I don’t know the exact temperature) for around 2-3 months before I sent it and I’m not finishing the roll on the exact day I’m loading it on my camera. Then again, I’ve had rolls that I don’t finish in one go before and stored it for quite some time but the results weren’t like this.

Do you guys know what might’ve caused this? Thank youenter image description hereenter image description here
