The details on the dress help to catch my eyes more-luv details. The jewelry and flower also help to draw my eyes up towards the face, which has a lovely colouring. The detail work with the strings for the sleeve(both tied and untied) are very nice. The use of the reds and browns and golds are a good pairing. I especially like the use of light for the glow of the latern on the arm & face(and the reflection of it in the door). Your fireflies are too cute, but as for the change in background, I don't honestly think it would make too much of a difference-this is due to the main focus being on the young lady and the firflies. All the tree limbs may perhaps be a bit distracting? (viewing the old version) and I notice your backgrounds are almost always detailed) If maybe the background was more of a ghostly hint of a forest, without too many details, then it may give a bit more dramatic feel to it, but I think this piece is quite stunning the way it is. Fantastic job!
