As long as it is not too similar to this; I let someone use a piece for reference once and they basically traced it, lol! I don't mind if people look at my work to get an idea of how to use water colors or apply paints, mix ink and watercolors, choose colors etc though!
Oh, for the pose certainly! That would be just fine Thank you for asking! And for using "reference" correctly, lol that one guy who traced has me paranoid after all these years lol! Good luck with the piece!
