Something I struggled with a lot are faces. I don't know whether it's that I'm actually bad at them or I'm just not happy with what I come up with.
It's time I started asking why. I took a break from work and doodled Gon...for no particular reason from memory. He just came to mind because I watched a few episodes of HunterXHunter recently. First one I drew was the top left with the X. I liked it but I realized it didn't feel like Gon. His eyes were too "Fuck me I'm cool." so I went with the more innocent open eyes and Gon appeared. I think I put too much weight on the eyes in my expectations in expressions instead of letting the whole face help them. Changing the lids was a quick way to almost make Gon into a new character which is why I made the third one with an X. Obviously you can use lids to express things like exhaustion or lust but it's nice to realize this stiff thought I had programmed into myself. After that I just started trying to make expressions with what I had for fun. I really like the crying face. I spent some time adjusting proportions and coloring the smiling one. I have trouble with symmetry and proportions.
And that's about it. Gon.
