Let me see alternative colors, though I like these. Why do you have the shadow beneath the graphic and above the reflection? Can you redo it in a way that .com isn't as prominent?
alternate form-factor and text treatment - very clean and bright with good use of whitespace - fresh, vibrant, positive...
(This comment references Entry #228) (shadow/reflection - tends to 'read' very well especially at smaller sizes. I will also provide a non-web version more suitable for print applications)
larger url/tagline, alternate colours, no refelection... (I'll be more than happy to work with you to your complete satisfaction now or after contest close)
