Welcome to the 'site, PJ. I suggest you try reviewing people who write stuff you like. In particular, people who review actively themselves tend to respond well to a good review. Even better, someone who reviews really well and has their own work ignored will reciprocate with an unbelievable amount of love.
In terms of what good reviews look like, I list three of my recent good 'uns, and also some good reviewers, on my profile.
