So I might be off on this, and if I am I apologize, but to me it sounds like I'm not hearing enough facial emotions, if that makes any sense. Try to emphasize the emotions with your face, and that will help form the feelings you want to express through your words. For happiness, smile BIG! BIGGER! For anger, have a scary scowl >:( maybe bare your teeth to get the feel of it- I did hear some good emotion from you in certain parts, and those were great! Also, I totally get what you mean by struggling with excited happiness, I struggle with that too. Let's do our best to continue improving!

#1: Some nice power from anger here, feels a bit unclear on the delivery choices. Like a rehearsal, similar delivery throughout; try and flesh out the 5W's and intention for your character so that you can be reactive and adaptive in the scene as you understand it and it unfolds. #2: Some great pace and energy in here, and I wouldn't be mad at some bright smiley areas (not all the time) to really help us feel what it feels like for "you". Overall, it's a bit hot (peaking) so with your power, a little more mic space and/or gain reduction will keep more of you in the recording wave.
