time-lapse photograph of stars

I was feeling sleepless in my apartment when i went out on the terrace just for a walk. Than i saw the polaris, shining dim as the sky was polluted from nearby lights from industries. I thought of taking this shot so straight away pulled out my tripod and set it for 3 hours with intervalometer of 30 seconds. This was the outcome after 3 hours. Edited a bit in lightroom android app.
