You’ve hardley even changed the original theme so there isn’t much to comment on
for the gui I only changed the top-banner, but most templates are slightly changed. I still beleive the topbanner makes it a little too clean.
There’s nothing wrong with clean but like Usayed said, you haven’t really done much to the template so there’s not much to comment on.
If you want to stick with the header image as it as, I would change the background colour and link colour to make the theme more “unified”.
Have you considered changing the background gray area to something else? That’s what I did with my template as well as change my header to something I designed.
