You should keep the front vent imo. It would look good on your skin. I gave it a go, not really satisfied of the look, but those sleepy eyes do look good.
Oh and you should make the 'sleepy eye'd light' white so they look like they are the smae headlights but one is working and the other one isn't
i kinda like the skin you make there and im wondering, how did you make those screws (is that proper english?)on that skin, id like to put them on some skins of meself
