Logo Design

I have made some rough drafts for the Logo ... of Tech Zephyr 2009 ... which is actually renamed Tech Zephyr 2k9 only because we have had a event in 2009 already so just to be able to distinguish between the two events we have made it 2k9...

Here are the rough drafts of the logo:

First Specimen:

Second Specimen:

They dont seem different but when kept side by side or viewed in image viewer of windows the difference is known:

As can be seen from above in one I have made a smaller "T" and also a smaller "Z" and I have made extensive use of danube font and copperplate gothic bold for the "Z".

I have made the 2K9 look broken to bring out a different feeling . The planet earth is to smybolise the efforts towards saving it from global warming ...(recent victim being India itself coz of El Nino).My previous attempt at making the logo:

So lets Just see if the logo gets approved or I have to go on working on it for some more days.
