Yes, I should pay more attention to things I like and clarify for myself why I like them. I tend to only notice things when I don't like them, a great design tends to do its magic in the background.
Did you design it from scratch, or did you use a framework that you customized? And do you design in Photoshop first or straight away in code? I have one project in mind right now where I basically started with bootstrap, put all the components for the functionality in, and now it looks like such a mess that I don't even know where to begin in cleaning it up any more.
