Create a sprite character?

Hello, I am trying to create a custom character. I know how to add one, It's just the "Custom" part im having trouble. I'm trying to create a character that is just a flat image.[(https://imgur.com/7mEnKnV)]

im not really sure, but you can try this:

make all the required parts for a starter character, then make all the parts transparent

then make a "sheet" in the middle of the character

then you add two surface guis to the sheet, make the guis cover the whole front and back side

then you add an image label under each surface gui

then upload the image you want to roblox and put the image asset id into the labels
