Hi Nicholas--Welcome to Etsy. I am not photography expert, but I know what I like, so I will give you my perspective.
First, I would like to see you add more to your shop. I respect that you are only posting your best work. I hope in time you will post much much more.
While I like your creative titles of your B/W flowers, I would like to see flowers the in color. I do really like B/W pictures, but more of larger vistas, or even people, and street scenes old houses and twisted trees etc. Your picture of the capital is nicely done, and is a good example of regional interest subject matter. That often appeals to buyers from that particular area or who have vacationed there.
I would also suggest that you take your camera with you lots of places and take pictures of things that are not just pretty, but that capture your imagination. Images that make you want to know more, or that stir emotion, or sentiment.
I hope my critique has been helpful.
Best of luck==
Sally Tia
