May want to consider smoothing out the normals on these three edges here - I'm assuming this is a hand painted model meant for a flat shader type, but probably wouldn't hurt to clean it up.

I think it could help strengthen the silhouette of the candle if you added a melty/extruded rim around the candle top, and also made a few more drip pools along the base.

You have nice highlights on the metal candle stick - maybe consider adding some sheen/highlights to the top of the wax here as well to reinforce the material type.
