Don't animate her boobs. For one, female players dislike it. Plus it doesn't really look right at this sprite size. Just my advise though!
As a female gamer, I would like to refute this. I have nothing against boobie jiggle. I do have to agree that it does look strange at this sprite size, but I think the real problem is that they are swaying side to side or something. You don't want that. It's unnattractive. It makes her look like she has flabby granny boobs. If they're going to bounce, they should be bouncing up and down. The other thing is that she doesn't seem to be moving very fast. She's just walking. You have to get to a nice bouncy jog before you start to get boobie jiggle on the level that would even show on this sprite.
Anyway, other than that, it all looks great.

I like #2 for your logo. I like that long tail on the H. You could decrease the size of "to" if you wanted to. That would help separate it from "Hammerdale."
