Really well done. My only suggestion would be to remove the redness around her eyes (make a selection around the eyes, and use Image>Adustments>Hue and Saturation, Reds to reduce the saturation and lighten it a bit)...

Some sharp angles on around the edges of the face, with a couple of noticeable points, but very imaginative!

Is using prefab brushes face painting?

If I would be able to paint I would put it onto canvas

Why I may not use brush? That's bullshit. Red or green color may use it?

The fur's direction going sideways on the face looks odd...It doesn't looks "painted," so much as cut and pasted overlay.
Perhaps reposition the fur so that it runs from top to bottom...

Not painted, just an overlay.

Changed

On theme, but ho-hum.

I think "Painted" in a Photoshop contest could well include overlays, otherwise this would be a "digital drawing." If nothing else, you could paint the fur...

It was better with the fur. B&W photos are generally more "ho-hum" in a chop contest.
