Wow beautiful

Wow this was very beautiful bird here very nice setting and some nice feather texture to give it that realistic look here, no major changes needed as this was a beautiful shot here, Sketching is great sketching with color is great as well I love the details on this, The colors are dark but that goes well with this piece sometimes too bright of colors can really bother the eyes so it's best to use dark tones and muted colors, you really pay strict attention to details a quality most admirable.

The feeling is there

You're obviously talented.

It just breaks my heart that the scans look so dark. You really really REALLY need to edit the image after scanning. Get a Cannon scanner.

Also, the background coloring needs some fixing because it's unbalanced.

It looks a bit unfinished.

however, the bird/subject is the best part.

I guess fine art is your thing. :)

Nature, in all its glory

This is a wonderful sketch. The deep, brown tones make the picture look natural. I can just hear it singing.

Nice

I like the posture you gave the cardinal, its quite realistic. Good use of coloring and texture too.

Nice job
