As always, I'm captain negative...

• The ball/circle/A thing is disproportionately large to the rest of the name. It makes your name feel like a tail or some strange appendage.
• If the "A" is too large, then the "photography" is definitely too small.
• The letters in the name are spaced too far apart, making it difficult to read and causing it to feel like a bunch of separate units instead of a single name.
• The mark will never work small. Logos should work at the size of a quarter. If that happens, "photography" will never be legible.
• As Hen pointed out, too many stars.
• The colored version has way too many colors. The brown/blue is nice.
• Hen's version is an improvement; photography is larger (though not in a terribly legible font), and the A/circle is still too large to be in balance, but overall it's much cleaner. I'd continue down this path.
Some things to ponder:
What does the A in a circle mean? Is there a reason for it, or do you just like it?
Do you need the A in a circle AND the stars AND the swirlies? Or can you get a way with the A in a star?
(As always) I recommend hiring a designer to finalize your vision. You've got ideas, but your lack of experience as a pro designer will hurt you here. Just like someone who just bought their first point-and-shoot probably shouldn't be shooting a wedding; people with no design training shouldn't necessarily be doing their own logos--no matter how creative they are. That's not meant to be an insult, I'm just trying to advise you in a purely business sense. I want the best for you and your brand!
