I was playing with Pico-8 palette. Colors are nice ... if you want to do 'cute' pokemon game. Not if you want actually draw something.
But I did'nt give up - and here are results.
For me its rather strange color and motive choice. :D
You may consider it also as my first 'fan-art' graphics ever ;P
13 colors (from 16 color fixed palette)
about 10 hours of work - Grafx 2 + intuos and mouse
(Definitelly there will be more pico-8 stuff from me.)
