It is such a sweet little painting! I did not notice any of the imperfections you mentioned. It just pops so well from the background and the elements of reflection in the bauble are done so neatly! I can almost reach out and grab it, that is how it feels when I look at it!
What is funny I have a few baubles exactly like that in my tree too! You have an incredible talent and skill!
As an amateur myself, I have never touched glazes or other mediums that help while working with acrylics, but they are on my list to acquire. It seems like a lot of fun from what I gather.
