Twentyfor: folders 2

Still working on that 24px icon set. I want to get it right so I've taken in account the feedback I got and added some changes that I thought of.

I changed the color to something more grey; don't worry, there will be 4 color variations.
I added some shades to the folder.
I darkened the border of the add glyph.
I tweaked the star glyph and set an outside stroke instead of an inside stroke.
I tweaked the heart a little bit.
I enlarged the bookmark.
I added some highlights on the padlock.
I added shadows to the secondary elements.

This is a rebound; you can compare this shot with the original and tell me what you think.

If you still have suggestions, you can submit them.
