@ArtistErin Oh, I see! I didn't look properly and thought that was his tail. It might be effective to leave out the foot altogether and just show the bear from behind? Other than that I think the bear is perfect. I notice from your website that your people are usually pretty realistic in their proportions, whereas this girl looks a little more rigid and flat. That arm with the balloons looks quite uncomfortable. Also the bear is looking down at her beautifully, but her gaze leads to his sleeve; maybe tilting her head up a little would also make her look more adoring.
I hope my criticism is helpful! All the work on your portfolio is lovely! My 5year old daughter was admiring them with me.
