Thanks guys.
I made the mistake of starting this sig in CMYK and not making with web purposes. It now looks so different in Photoshop compared to the internet. Live and learn I guess. In my version I was able to give the light a lot more depth, but I don't think the effect was even applied when I uploaded it online (even after changing it to RGB and the Internet setting).
Btw, it is a skull. Original render:
