With critiques, mostly I just want something in depth, beyond the usual spelling/grammar corrections. I like to know what worked well and what bombed, what parts feel slow or flat or awkward, where things need expanded or condensed. A critiquer should be looking for plot holes, for inconsistencies, for dropped storylines. I'm more interested in their thoughts on how the story works as a whole than individual line by line corrections (though those are good/necessary too).
