I can see some people are using custom avatar with WO hat. You are editing the WO hat and using that. If I'm not wrong, xhomerx10 is the creator of the avatars and thus, you don't have the right to customize it without his permission. You should ask first to xhomerx10 whether you can edit the hat or not.
Just my two cent.
I don't know what the others did before they have customized-avatars (cap, especially) and applied here. But for me, it is as below.
How about this cap? Honestly, I did not make the cap, xhomerx10 made it.


I believe xhomerx10 is fine with such caps, even people customize it but sure it is the best if you ask for his permission (in private message or public post) before doing customization.
I asked his help to create the avatar I am wearning now but he misunderstood my idea and created the BeardedBaby cap above. I am sorry the BeardedBaby because I did not ask for his permission to use the image of bearded baby.

By the way, I have a proposal for
Best_Change:
If you see good positive effects from customized avatars, you can move further to open avatar campaigns, I am sure some guys from the ChipMixer gangs will join the party. They are free from avatars and they are undoubtedly high-quality enthusiasts.
