welcome to the family. not to sound harsh or anything but having three "titles" in your signature pic that are all different looks dumb. --> "LOOKS:" "SPEEED" & " Sound System". If i were you, i would make the titles different color from everything else and make them all the same, either all caps followed with semi colon, all spelled correctly, etc. id also shrink the text size for the stuff you listed thats on your car, and make the "decals" you have at the bottom all the same height --> either match them all to the height of the "pioneer" image, or increase the height of the "pioneer" image. if it were me, i would get rid of the brand names and put your screen name in there somewhere.. or some quote you go by...
just things you can take into consideration.. everyone has their own personal preferences as to what looks good and what doesnt.
