I suppose it's kind of like saying “should I make my ecommerce site look exactly like Amazon”? It is an instantly recognisable brand for many people, and instills confidence for some, as well as having many other connotations.

In your case, you have unwittingly styled your blog to match what is a very recognisable brand for some people.

Personally, I would assue your blog was part of Svtble, and on finding out you aren't my gut reaction is that you are trying to trick people into thinking you are.

I would change the theme somewhat (red logo in a circle with white/red border, Svbtle logo in bottom right should absolutely go) or use a different theme.
