The artist has been paid in full.
They have posted the finished (shaded) image in their gallery.
Everything up to this point has been great and I was prepping the positive review.
Then I ask for my copy and was pointed to the flat color one -- which they described as the flat color one.
This artist doesn't even offer flat color as a commission option.
Nothing is said about only getting the heavily watermarked small gallery copy as the finished image in their commission info and they have no FAQ or TOS.
