Hi! I'm so glad you enjoyed the plans!
Regarding the hinges, I'm not sure if you don't like concealed hinges in general or the specific brand of hinges I used here. If it's the brand you didn't like, you are more than welcome to select a different brand of hinge for your project.
If it's the type of hinge (concealed hinges), these are the standard style of hinges used on cabinets because they are easy to install, replace, and adjust for a perfect fit. They come in four main types based on the type of cabinet and type of door you're installing. In this case, this is a face frame cabinet with overlay doors, so face frame overlay hinges are used.
If you didn't want to use concealed hinges, you can certainly swap these for butt hinges if you prefer. For more information on choosing, installing, and adjusting concealed hinges for your projects, see: https://youtu.be/l06Up00YRU0
