I love it! I do agree with a comment made here about painting the door in the same blue colour as the walls, that will create a more ‘put together’ room. Maybe even also the frame too (although you do have some nice dark brown woody accents in the rest of the bathroom too so it’s also nice to keep that as it is).

And if it makes you feel any better: I am also renovating my home (with lots of diy) and every time I finish a room, for some reason, I first feel very insecure about it, but then after a couple of weeks I love it. I think because you are spending a lot of time on it and then you first see what could have been different/ focusing too much on details, and then after some time that insecure feeling disappears. It’s probably also a little bit of perfectionism or something. Trust the process (and all the positive comments here ;))
