I am not sure I would also like to know how big it is and would like to see it in person to inspect the details but anywhere between 50-200 depending on things but it from what I can see is very good I have not sculpted myself I make steel armor and scratch boards but if you want my advice make casts and sell them for cheap because no one can afford 2000 but 50 to 200 they can and will by them and casts don't cost too much to make so you can make quick profits with little work those are my two cents and I hope they help.
No you wouldn't because as it stands on that sculpture you are getting paid nothing because no one can afford 2000, and making a consistent 200 apposed to hoping for the one 2000 is much better.
