Very nice! The feather texture is well executed. You just have a few stray pixels I see, like on the bottom wing and that white one on the beak. The border lines aren't really doing anything for the image- they just interfere with raven and distract. It would be nice to see the peice without them.
Really nice raven. The head looks pretty. I especially like the shiny parts around the raven's beak.
The white frame lines don't look too well though. Just as Sooba said they only distract from the rest of the image. Maybe you could make them less vivid.
