Thanks for the very nice comments. I guess what I would like to improve at, and maybe practice will help me improve, or maybe I will find I'm just not an artist, but there are two areas I think I wish I had done better. 1) the eyes, the dog, have very "kind" eyes, my rendition, the eyes look "worried" or "concerned". 2) the mouth line. The picture doesn't look like he is pouting, in my picture I see a pout.
Not sure how to do it better in the future. Like I stated, maybe practice. I know I have no artistic ability. I certainly can't draw.
