I'm not sure I haven't read the rules in like 3 years lol but I think the winner already gets DPs. Regardless, I don't think it matters. GFX competition is merely to see others making interesting stuff while adding some competition flavor to it.
What I agreed when I took over SOTW originally was 500/200/100 as DP rewards. I gave them out but recently stopped because Anzo doesn't deserve free DP and I can't be unfair to one and then extra fair to another.
