I am pleased to see that you are concerned as to which photo to submit, it shows you care!
However I think we need to start as we intend to continue, so you are the best judge of what you want to achieve with your photograph and you need to decide which is your best result. This may seem harsh but you are the creator and I am merely the tutor who can, and will advise on your submissions.
Take the first step, make your choice with confidence and let me give you my constructive critique once i see it.
I look forward to seeing your images as you progress through the course.
