Ah, those are some good observations. In regards to the buttons and such, half of that is due to simple negligence. The other half is due to mirroring some of the sprites and using them as the final versions.
As for the shading, the second-from-the-right fellow was shaded before anyone else and then put aside for quite a while before getting back to the other sprites. We'll likely go back and alter his shading to end up more in-line with the rest.
And as for the lack of a maid? Well, I think we can correct that. I'm sure that grandma has a sexy French maid outfit somewhere...
