A much better start! It allows us to critique one thing at a time, which will help tremendously.
Honestly, I don't see what the top horizontal line adds to the design. It doesn't say anything "fun" or "artsy" or anything like that...it just seems to "be there." I favor the bottom design of the ones you just listed.
The font choice conveys (to me) a contemporary, solid business.
Perhaps you might want to look for a way to convey the "artsy-ness" of your business with a (perhaps slightly) different font, or face of this font. A simple italic might add some movement to the logo...
Play around!
