Thanks all for the great comments.
I shoot those pics few months ago. Filtering and improving them itself a huge task and demanding more time and effort.
I was postponing that task due to various reasons.
WLM announcement gave me some encouragement to work on this.
Thats why asked this question.
Started processing them and improving my GIMP skills.
I agree that 700 pics from a single person for a competition is a kill.
I will upload them all to commons and add only top 10 pics to WLM.
