Sloths Draw

I did the second exercise from the last prompts, and picked two of these seven emotions to draw: confident, uncertain, frustrated, hurt (emotionally), flirtatious, mischievous, and tired. So, can you guess which ones I picked?

( cut for two drawings of faces, both worksafe and harmless )

Concrit is very welcome. Personally, I rather like how the first one turned out, the second not so much (one of the eyes looks really weird), but I decided to post rather than to fret too long.
