As said previously, the pix angle tends to exaggerate the angle. However, it's fairly typical for any cut to center recurve. Add a piece of leather for a strike plate, and it's 1/16 to 1/8-inch from center. IMO, that's a good distance from center for finger released arrows. The long shelf magnifies the angle, but it's pretty common on any similarly designed riser.
kibok: If the bow is vibrating at release, you may be shooting arrows that are too light and/or your brace height may be too low. I'd suspect the latter. If your limbs can handle it, try a fast flite type string. They're not only quieter and faster, they reduce limb vibration as well.
