Icons look cool, but it seems to me that the constant presence of the hand creates two problems here: 1. It dramatically reduces the clarity of the signs (the dots and arrows), which is actually the part of the icon that DOES guide you (think as well of small sizes/low resolutions), and 2. (as ronaldx mentions already) it adds a repeating motif which I'm sure after a while might become uninteresting, and also may very much graphically define the app it is used in.

As a suggestion, perhaps the relative sizes between the hands and the signs could be reconsidered, and a more abstract level of representation of the hand could be thought of.
