The fact that it's paid per hour DOES matter, he agreed on per hour so it's obvious he pays per hour. If he keeps asking revisions and keeps bothering the artist then it's obviously going to cost him more. You just judge the work with the price but it's not how you should since there wasn't a set price.
this is only one example of the part where he does like it, except the party hats:
http://puu.sh/45D7e.png You twist his words, you act as if he paid, then when kina give it to him he didn't like it at all, blabla. He even used the signature on sythe for like what? A week? After that he posted this report, isn't it a bit weird to say you like it except one thing (we'll leave that up for dicsussion, can easily be removed it's no major thing) And uses the signature. Then one week later you don't like it anymore.
