Dude UI (and anything to do with looks) is always a subjective thing. Some people will like it and some people will hate it. I know every dev wants their UI to be loved by everyone but that’s a fools errand as there are always people with opposing opinions. What matters is that that you like what you have created. Also know that there are people like me and many others who use photon daily and love the design. Don’t let subjective opinions get you down.
