It's really more of a font choice than a logo.
It works better without the oval, which reduces it even more to a font.
I think I'd try a different font, but I'd also consider offset stacked copy, & an icon.
Maybe "Sign" above and to the left... the "g" drops in front of "Shack"... and to the left of "Shack" is a little shack icon...
or even stack "Sign" up & to the right, "g" hangs near "k" and shack icon is to right... and "vinyl lettering & graphics" is illustrated like 3 little stacked sign panels posted adjacent to the shack, in similar shack-y style... this would balance "Sign" into the center of the logo...
