The logo will be mainly visible on the website, e-mails, and the paperwork handed to the client (mailing, Welcome package etc). It will probably be printed in black and white, and should not be denatured
Pyxis is the greek name for a compas. The logo should at some point represent that compass (The X letter could be a compass, but not necessarily!) The logo should be telling that pyxis.ma will help you drive your business.
Pyxis is also the name for a small constellation, references to stars could eventually be on the logo, only if it is does not make the artwork overcrowded.
Also, the stylized part of the logo should not necessarily contain the ".ma". But the "pyxis.ma" must be somewhere on the logo (see the angel springs logo I have attached).
Finally, the simplest, the better : The logo should not be denatured if it is displayed in a small size, or printed in black and white.
