Dunno about the four lights personally, hehe i guess im not a big fan of stating the obvious. My thinking was keeping it along the lines of the banner of the forum. But as with anything, comes down to personal taste
Trying to please everyone is mighty difficult when you start including colours, symbols and images etc, so Boof is probably right; the best option would probably be to stick with the original www.skylinesaustralia.com sticker that Miss33 got - it fits the brief perfectly; discreet, simple and not over the top. Maybe just done in the "updated" skyline typeface?
Anyway, i dont even have a skyline so what i think doesn't matter LOL
