#220 looks good. I like this shade of orange. I think I prefer the dot on the "i" from #222 more.
Can I see some variations of #220 with
1) slightly larger circles
2) Glass effect on the circles
3) Glass effect only on the orange circles
4) A shadow beneath the image like #182
5) Whatever else you can think of...
I think the font size needs to be bigger relative to the logo - but this can be sorted out at a later stage.
Thanks,
Steve
P.S. If you win, can you provide art work in Adobe Ai format?
