Before everyone cries out loud "Yes!", I have to remind you that I am a human like you, which has his moods and times in his life. So if I´m not in a mood to do something, you won* t see anything of me.
I am doing currently 8-bit sprites, which aren´t so difficult like the 16-bit ones. If I am in the mood I will even do for you 8 and maybe even 16-bit.
One thing though, if you request them for your own games, so let me know of your previous work, it may make me anxious about to create them for you right away.
