The bright colours in this caught my eye, but I really love it because of the lily/"missing you" theme... I'm missing my grandma a lot too. Anyways, you did a great job with this photo, it's very beautiful. I'm very sorry to hear about your loss.
I think I have seen this type of flower before, but never like this. You take the ordinary, and make it seem extraordinary. I'm sure your grandmother did the same in your life, too! May she rest in peace.
I like how you captured this flower because there is a dead one underneath it which is realistic to how flowers normally are, with the ones yet to bloom on top. In my garden I see this a lot and I always found it particular. It's not just focused on one flower, it's showing all elements of life.
