There are only 44 images to look at. It's not over-bearing.
I think your location shots are generally more interesting. The location surroundings often give you pose options, and make your composition more interesting. Most of the studio shots are not lit in a very professional manner. The background is usually bland. If you use backgrounds in a studio shoot, they will look better if you care about how they look. Use colorful gels on them. Try using a fog machine, pumping smoke behind them, and lighting the smoke from below or from the side or top.
Your location shots seem clear enough to continue to consider using them.
I prefer shots that have the cosplayer not looking at the camera. Most of your portraits have eyes at the camera, limiting your poses.
