Ok, cool. Yeah, I normally don't submit such simple logos, but I wasn't quite sure about how to approach this one based on your drawing, so I wanted to make sure I was at least headed in the right direction before diving in. :-) I can definitely add more detail, and color.
By the same token, a great logo works just as well in black and white as it does in full color, just as well at 1 inch wide as 1 foot wide. so given the nature of the design, we don't want to detract from the message by getting TOO busy. :-)
