First...my standard intro to anyone "new" to me on this forum...
My comments or suggestions below are not a criticism of you, your model, your talent or skill. I offer them in a friendly tone of voice and with the sole intent to help you with a second POV and set of eyes. If you read sincere questions and simple suggestions as "criticism" of you, then you will miss how I am trying to help you.
Of course this may be your own "style" or your own "vision" and I suppose we can assume that the images look just like they do because that is exactly how you like them. That is OK too. It just shows that there are differences of "opinion" on what looks good. IF these are exactly what you want and like, then by all means continue making your images look like that and have fun doing it. I can only speak for myself and what I do or do not find appealing in the posted photos. As I always say: "Follow your own muse."
Unusual costumes can make for interesting images.
I like the use of slow shutter to show movement of the crowd.
What would I change or do differently? Or is there anything I don't like?
I think the composition is not as good as it could be. There are two subjects (groups) in this image (photographer and superheroes). As shown (or as composed here) the left most group/subject (photographer) is cut by the edge of the image frame. Yet, there is room behind the superheroes (image far right). I would prefer to see the photographer (one of the key subjects of this image) NOT cut by the image frame.
I hope these comments help you.
