Thanks for you entry. I really like the PI aspect of your design, a little FBI like. If we can find a way to make the overall logo have a bit more depth that would be great (whether that is with shadow or reflection, i don't know).
Dear CH, Thanks for your attention. I'm sorry ... While I was not able to immediately make changes in design because I'm still not a full member of the logotournament.com (I am new designer).
