Would it be too small for a favicon? with FUELED being outside the circle, just for the icon of the brand - how would you design that? I like the original you created most for the logo itself. I'm thinking about other applications and having an icon in addition to the logo

I like this one. Would like to see how this would look in a circle or square for the favicon. Either a variation of this logo or an icon.
