yeah... your font use is most mismatching with the theme of the sig you are using. and the multicolor background isnt helping with a mostly grey and white scheme...
First off is a redesign of my sig, since the Avenger has now become my main craft. Ok the sig.... Avenger and Upholder on one side and the girl as you designed in my current sig on the right, using the current back groundif possible.
Second order is that comm id avatar, not a priority though... If its possible can you put her in some civilian kind of clothing in a base of some kind? If you dont have that avatar stored I will provide it.
