Did I see a raven?

I was walking to go and get Wolfie from school and passing by one of the town's allotments. And I saw a huge corvid. It was really big. I suspect it was a raven, but I cannot be sure as I am not really an ornithologist, not even an amateur one. Either that or a really big, oversized crow. But I think it was a raven. I tried to take a picture, but unfortunately it flew away before I could. I will keep my eyes open for next time.
