At this time I don't have a better name, but I can say this... What ever name you pick do not put a object in the name, because if you do, then people will assume that is the "art" you are making. So with that said "Navy" and "Wolf" shouldn't be there IMO.
If you are really going to get into this... I would name it something that has to do with "you", as maybe the 1st letters of your 1st, middle and last names or your complete name or if you plan on using a AKA for your true name (how you will sign your art work). Now if "NavyWolf" is going to be signed on your art work, then that should be the web site name (NavyWolfArts).
Don't worry about making the name "cool", because "your" art work is what is going to get people to your site, not a "cool" name.
What ever you come up with, I wish you luck and don't forget me when you make it to the big time.
