I like your photos. That being said, I think it's hard to succeed on Instagram specifically unless you have a very well-defined theme or style. There's nothing wrong with trying a little bit of everything, but I think it's also understandable that the people who initially followed you because they saw a great portrait you took may not be interested in your landscapes. I have an Instagram account that's private and mainly followed by my personal friends. I post whatever I want on there - my paid photography work, my life updates, pictures of my cat, etc. but I also keep a separate, public account that's strictly for my professional portrait work. I think having that separation helps for retaining interest.
