Thank you very much for the suggestions and in-depth icon criticism! It really is helpful! :D

You're right, though. I'm trying to branch out to different fandoms and subjects and I've been working on more live-action icons in recent posts. And I am definitely more comfortable with iconning art/animated/cartoon subjects as opposed to live-action/photographed subjects. It's not that I enjoy animation over live-action but I get frustrated with live-action subjects because I am confused about the color palette or the cropping or how to get an interesting composition. I'll definitely try to work on my cropping in all kinds of icons though! I'm comfortable in cropping so that the subject is recognizable but I should really try to see what happens when I crop more "artistically". :D
