Day 03: Autumn

Given autumn is my second favourite season, and actually as far colours go it's my favourite, choosing a single picture was always going to be jolly hard as I have so many beautiful ones.
In the end I decide to go with this one as I do love reflection pictures and this is one of the best I have seen.
