You can download and edit them to your liking! There are three sizes, the original, the steam icon, and the 100x100 pixels icon.

(go to 'bases' then 'sergalitos' and you will find them scattered all over the place)

Rules.
- credit me in your profile, and add a link to my profile. <- minimum requirement
- For free use, you can make an avatar for yourself and for your friends!
- do not sell it or make a profit with it. It's free! (you can charge to edit or pay someone to edit them for you, but do it privately, ok?)
- you can change the lineart, but that will work better if you use the base with no shading! :D

Tips;
-If you don't like the grey shading from the base with shading, you can add a layer filled with red/blue or any other color on top of your drawing, set layer style to multiply, and opacity to 25%. If It does not look good, try changing the color to fit your character's color. Usually, the best color is one similar to its palette, if red, use red/pink/orange, if black, use blue, if green, use green, and so on
-Color the sclera (eye white) and teeth light yellow. It gives a nice look.
