I'll take the job (if u want me to). Here's my CV

1) I'm online between 3:45pm-12:00am during the week and 3:00pm-6:00am in the weekends (Times are approximate, GMT)

2) I won't show ANYONE the tileset. To prove this I'll give you a small batch of my set that you can show to the entire world before it's supposed to be released (if I do exploit your set)

3) I'm a BIG critic, I'll give you an honest remark to the slightest detail and give you ideas on how to improve them and what extra stuff the set needs.

There, that should do it, answers all the criteria you need. I'd just like to say that I LOVE your approach to a tester. You ask them to make honest remarks and 'get to the point' no matter what they think. It's the way I do it, and I love the critics to bits! Always good at what they do, and the extra opinion is worth it
