Thanks, but no need to. There is not much experience needed for pictures like this, some very basic knowledge is the key for a good sprite picture. Believe me, Paint is prolly the most suitable program for sprite editing/creating since it has only a basic but direct interface, enough for making good sprite pictures.
Side note: I have a 2425x1985 sized sheet full with sprites, plus another 1542x995 sized sheet for my Shy Guy and variations. :lol:
