High resolution model of Imp

Some time ago I find in net very good looking model of Imp. This will be forecast of new models pack for Doomsday, or something... But, unfortunelly I don't remember link to this site. I searching in google but without result. Does anyone have some links? (or maybe finished models)?? BTW maybe someone have links to original Imp sketches from Id? Or any other good quality sprite/graphic?

Are you thinking of the (currently inactive) jDoom Modelyard?
If it looks familiar - the download link for the Resource Pack still works.

Thanks, is exactly this
