Emotion - Spectrum of happy (Patreon)

I'm trying to play around with expressions to get the hang of his face structure, and i'll start with "happy" first.
The hardest thing about happy is Baldus isn't a happy person xD, so there was this voice in my mind that keep telling me that i shouldn't "push" his happy emotion too far or it will feel off ( as you can see from collum 2, the expression next to the smiley face icon is a bit off )
If you like any particular one, let me know your thoughts !
