Logos and drawings

I've wanted for a long time try design some kind of Logo for my Black Swans.
Keeping it simple and also making look good is hard, somehow I also would like to have own coat of arms for them. (That I'm definitely going to design someday soom!)

so my to-do wish list is

• Logo
• Watermark (have "Martza" in it)
• Coat of arms
• Business card

Here is some my old ones and tests~

Logo test, cute and simple~

My first watermark test, but sadly it's not clear enough to see

My newest watermark test, just have to think if I can make my name to fit prettily
this is something I've wanted try for a long time
