Map Icon Fixing & Can gore sprites be changed?

[ZerKoma]

I'm currently trying to make a resprite pack for the Arms Dealer turning him into the Chinese Mobile Npc...
Here's the map icon: --->

The sprite sheet worked but the map icon isn't working and I don't know what's wrong with it...
I also wanna know if it's possible to make resprites for gore cause I want to make this texture pack feel almost official...

If anyone could give me some advice to fix my issue and answer my question then I'll greatly appreciate it!

I think because it have larger canvas size than original arm dealer's.

Is it probably the hat He's wearing that makes it too big?

Not just that, you will have to fit it that image, ...

Okay, I'll see if I can do that...

Gore sprites can be changed. They are labeled "Gore_X"
