If you take a crappy website... and then you draw out a few screens of that visual design... and change some colors and borders... (and it not even a real interface) (just a screenshot of a photoshop document) (and it doesn't work) (and it's basically the same shitty interface) (and it's not real) (and you never tested it with users)

...and you are feeling like you have imposter syndrome, it's because you aren't a UX designer. You need help. You are deeply delusional.

We can help you - but you have to be really honest with yourself...

You're going to have to do some real work, read some books, and accept that *praise* - is not the goal.
