You're doing a beautiful job with your grandma! She looks very alive. I think the collection case is extremely well done as well. I can't even imagine all that painstaking detail!
I am far from an expert on composition, but my feeling is that the adjacent furniture along the sides of the painting create a sense of being boxed in. Also, they keep drawing my eye as they don't seem perfectly plumb. I'm sure this is due to the photo and not your piece itself. I think those verticals could be superfluous and may detract from the beauty of the piece.
I really like the middle photo, where you have cropped your grandma to a 3/4 view. The surface of the seat looks perfect in this one, whereas when I see the whole picture the seat looks somewhat flat to me although I think that the material drapes over the side.
I hope this doesn't sound too critical, because I really do think this is terrific (wish I had done it
)! Just wanted to let you know what seemed to stand out for me. Your grandma is very beautiful and youthful looking. I can certainly see a family resemblance!
