Hi Indra, Good Afternoon,
Thank you for your entries. I definitely like the classy look of white and black and the overall feel of your designs; however the first letter of my name is a "P" and people looking at those logos won't know what my name is.
Not a big fan of the rings as well. Classy, with a touch of fun, the tower could be part of the logo but doesn't necessarily have to be.
Thank you,
Paris
