I am often somewhat amused by the ambiguous information given during and afte the curation process, and as to how helpful it really is:

While I am pretty sure I get the desire to - in a glance - give the member a chance to avaluate what curators are thinking, I really find it difficult to make it meaningfull in the context of a submitted photograph. I guess it comes down to the number of curators that actually is asked to give this sort of feedback? If only a few actually give this kind of feedback it seems evident that there is a high risk of this happening. Going through my own images and the feedback I find on them, shows a high propability of this sort of thing happening.
I would propose that the curater is given a choice of either expressing what they like OR areas they think should be improved, simply depending on ther curating choise. If a member curator 'approve', ask him/her what he/she likes about the image (and in doing so answer what the most predominant feature was them to approve). If they 'reject', then ask them what he/she thinks could be an area of improvement (and in doing so answer what the most predominant feature was them to reject).
This could be integrated in letting the approve or reject buttons act as a "mouseover". Mousing over "reject" could automatically reveal the "Main room for improvement?" options. Mousing over "approve" could automatically reveal the "Main positive feedback?" options. The user can still chose to simply click 'reject' or 'approve', but if they take the extra step to also indicate why, curation rewards could be two points instead of one.
Perhaps this type of feedback would be less ambiguous and more useful then?
