I knew he was trouble

Hey guys. So it happend. Inevitable. You know I was tell you about a client that order from me but he didn`t say anything after? Well he was back. But this time with problems. He is a guy from Singapore( love that place, wonderfull, although some say that is full of people who try to trick you). He is doing some t-shirts with some nice views and place from there. All good. But after I did for him a super cool draw (I mean it looks super good), and I had him check it up on me,with pictures send him( the sketch before draw, for approval two times). He has then his first revision: The purple cloud are to much"(I get it that) but then he told me that some lines from the bottom are kind of too much. At first I tried to hide them in photoshop. At the second revision he said like: No, I want the lines more like visible, like more bold. Witch I did it. Of course it end up not so good and he didn`t like it. But why he told me about that lines? Beause my draw where painted by kids and some of them have autism. Like...What? I though that he will print my draws ..not..like will be painted by kids. And the thing was that those kids will not understand to reproduce those lines. Wtf! I said in my mind. Then let them paint whoever they can. After all I try to tell him that. But in the end he got me 3.7 stars review.  I guess I had to read his mind and know that I have to draw so that some kids could reproduce my draw. I have no words. I give hime 5 stars, but at first I didn`t even to give something. I will let you guys the 3 draws that I send to him. What do you think?
 Mention: It cost 5$, and I get 4$ (I wanted to raise at 10, because people have more and more demands but I guess now I can take good bye from painting on fiverr)
Update: He is sorry for that 3 stars, but he though that I need improvement in my communication skills so he had to give that low stars. I told him that he could tell me that after, and/ or say in the review not to  et down my stars.
