After a week, I finally got to finish painting this shirt! I used the original artwork of the Japanese version of Super Smash Bros 64 and added the secret characters on top. I'm really happy and proud with the results! I particularly like how the logo looks like, haha.
The whole T-shirt is hand painted by me, and I don't own the characters, logos and blablabla. All the rights, lefts and middles to Nintendo and its friends.
