In browsing Patreon, I followed many artist. In all of them, I found one japanese artist I like : Asaki Takayuki.

His page here : https://www.patreon.com/asakitakayuki 

As you can see, he is an hentai artist who produce doujinshi and all. But I attracted my sight is one post of the 4th of december where he talk about Skeb. Skeb is a japanese website who permit to commission japanese artists. Depending of what you want and what the artist do, it can be from 3K yens to 300K yens.

By curiosity, I decide to make a try with this artist, on Skeb. The system is in beta but it do what I expected.

In the afternoon, for me, I planned the commisssion. At the beginning of the night, the commission was acepted. The day after to the beginning of the afternoon, I got my commission. 

One thing : the system expect one picture to be delivered. If you want more pictures, ask the artist to put them in the psd and extract them youself. It's like that I got two versions of the same picture.
