What price for the 4K image available for new "Tier3"? (Patreon)

According to the survey " Which image resolution do you prefer?" many of you want a 4K image.

So I'm going to add the 4K images very soon :)
It's gonna take a lot of work because I have to take each pose one by one ^^ to give you an idea, a 4K image takes me about 20 to 30 minutes to be processed by my computer against only 5min for Full HD.
Which is why I preferred to create a new Tier3 with 4K image available.
I hope Tier1 and Tier2 won't hold it against me ;)

I'd like to know what you think about this and vote for the new price of Tier3 you'd like to have. 

Thanks for your support :)

See you soon !
