Hi Ashley,
Thanks for submitting another assignment.
Your choice of a blue grad filter here is interesting given the sky is already quite blue! Often when people use a blue grad filter they are trying to cool off the color of an image that is too warm.
What really matters here is that you’re playing with filters and learning how they impact your images. In this particular image (which I’m not sure is sharply in focus) you’ve seen what a grad filter can do.
I would recommend you trying this filter on a sunset or a landscape with a dull sky to add something a little extra to it.
Did you get any other filters? Have you tried using them at all?
