Brandon James Greer is a great pixel artists who I’ve featured previously (see: A Sprite Analysis of Pokémon Red/Blue/Yellow) and in the above tutorial, he tried his hand at creating Chrono Trigger-style sprites for Final Fantasy VII characters.
With such a small number of colours and a limited grid to work with, he put a lot of character in the sprites while maintaining the general style of the originals. So if you’ve always wanted to see Cloud, Tifa, and Barret in 16-bits, now’s your chance!
