I love that thorn wreath behind her! You did a good job here, Katy. I think the shadow on her dress and form are good but I do see the disconnect on the silhouette shadow. First thing I noticed is it does not share the same silhouette as her. The hair strand on the top of the head is missing and the hair strand on her shoulder does not exist yet the shadow suggests it. Judging from light source, the shadow could also be lower I think. Lastly, since she is casting a shadow on the wall, one might expect the wreath to do so as well, but that's a minor observation.
