Meet Rage, my shameless self-insert avatar. The name of the set would be RagingGamer or just Rage.
I'm not the best spriter out there, but I've tried my best.
The Head Slot doesn't contain actual hair, only the headphones. I added the hair as in reference as to how the headphones may look like on the character with hair.
I realized that Terraria has no official headphone vanity, so the headphone can really be any design, as long as it is actual headphones.
The name would be Rage's Headphones/Head.
The Body Slot is just a normal jacket with a white shirt inside, nothing special really.
The name is Rage's Hoodie/Jacket, somewhat based on the Eskimo/Pink Eskimo Hoodie.
The Leg Slot is also just a pair of dark blue jeans/slacks with dark sneakers to complete the look.
The name is simply Rage's Bottom cause naming the jeans and sneakers separately is quite the hassle.
This is how each Slot would look separately.
It would be an honor to have this added into the final update of Terraria, but if it doesn't make it, at least I tried.
Thank you and Godspeed Terrarians!
