Dear lyratah,
No problem to put the logo on a white background... I'll show you...
and you can use both, for example: black background for the web, white background for the print...
Incorporating symbols: Be careful, if you multiply different symbols, your logo will be less powerful and efficient, the eye (and the brain) cannot remember too many things at the same time... it's confusing.
a lamp lighting the way: i think it's too concrete (and there is still a light in the center of the logo)
a winged lion: this symbol is very common in the financial surroundings, a little bit aggresive, no?
an eight pointed star: good idea: i can incorporate it in the center of the logo...
Thanks for your comments, you'll see new versions soon.
Good day, Sunshine,
Satto.
