Happy: Great energy but pace is making you a little rushed sounding and breathy. You certainly have more time pre 30s hits so might be a place to consider talking more TO someone IRL so that it can balance the pace a little. Clarity gently suffers at this pace and certainly the ending had that flub.-

Sad: Strong emotional work here, very affecting. So much emotion that we even get the challenges of it in 38s as voice breaks on a word. But that is such strong commitment and we could go again for clarity on that while keeping the rest. Very nice.
