As you see from the (lack of) activity in this thread, we still don't have a sound leader. So Enrique, as art leader, would probably be the best choice. However, you can also just post them for display on the forums for community review.
You probably know the requirements, but most sounds should be rather short (a few seconds), and animal sounds are best when there are a number of variations (else the sound becomes boring), however, it's still important to keep them recognisable.
