I have been thinking about the same thing over on P...(that would be short for Psyche lol - now I am getting with the net-speak).
I like the first one but I also like the pic of the planet with Earth in the background...please keep that or try to incorporate it in the banner somehow. I also like the teal green background cos blue and green are healing colours and the background and earth pic have these in them.
OOPs...this was supposed to be about the banner, right?
The first one reminds me of Native American Indians for some reason. The second is very slick. I think you need to find a middle ground...but meh, what would I know? I can't even find where to change the font size for my posts on P, let alone change the font style of the title of the board! Maybe someone else should answer your question, Blue...
