The isometric art was definitely different, but it’s certainly not a bad style.
The combat was solid, but the default RPG Maker weapons appearing don’t really fit the art style. I also think the combat was too easy, as I defeated the final boss by myself, with no allies in about 3-4 turns. The story was also a bit weak, not really going into detail as to who anyone was. In addition, the textboxes were cool, but having no backing makes them pretty hard to read. Mapping was the best part of the game, and you created a really detailed environment.
Overall, solid showing, and I can tell you put effort in, especially in the mapping. Keep it up!
