I uploaded this pic on fotolia and they declined it as they felt it would not attract many buyers.I have tried again as in the past I was able to get 1-2 pics online by resubmitting them.What do you think of this pic?I have other pics which are similar.But this one had some motion blur near the pigeon's neck and so I decided to give it sketch effect and now the blur isn't visible + it looks really artistic and unique.Atleast that's what I feel.I do feel that this pic has a conceptual appeal.Any critics would be appreciated.Any ideas on how this pic could be presented to get it online?

Lastly, do you know of any websites that would accept it under their creative category or something like that?I mean any agency that accepts such pics with applied filters.

I will get an approval from istock today most probably and my application on alamy is pending approval.I am eyeing inmagine.I am already on fotolia and dreamstime.Just in case if that helps.I am an amateur.

Thank you.

I can hardly tell what that collection of pixels is supposed to represent.  I would stop playing with PS filters if you are serious about submitting.

Pigeons don't sell. Doves yes (in flight), pigeons no. Swans don't sell either before you reach for your sketch pad. Puffins good, swans bad when it comes to stock.

Even from a thumbnail, this stands out immediately as a simple filtering - it doesn't look like a real sketch. I wouldn't spend any more time on work of this sort for stock - even if you did a better job with it, as others noted, it probably wouldn't sell.

What made you think this was unique? Either as a composition or technique?

pigeons? exciting! : )

Comment if you wish to..

The cricket ball could work as a stock shot but it would help if it were larger in the frame (it is the subject), centred one third across frame (rule of thirds and all that) and especially sitting on grass not on dirty concrete. That would place the ball in context as well as providing much better contrast. You probably need to lie down and shoot it from a lower angle too. Buyers scan stock searches rapidly with images at thumbnail size. If you want to sell your images they need to have visual impact.

I don't use PS filters but this 1 had mild motion blur which was impossible to fix so I thought I could present it this way.It's quite a big learning curve.But photography is my hobby.

Absolutely, but you'll need to learn to keep your hobby away from your stock work. Well, not totally, but some things aren't stock. Doing these filter things are fun for your own use etc, but stock has strict standards which we all have to climb a steep learning curve to meet.
One thing that might help is to compare your photos with those which are selling well on the agencies. Not that you should copy what's already there, absolutely not; but you can think, "Why would someone buy my photo of X rather than those which are already there?"
