It's looking interesting, as always I like your reddish shadows. The concept is nice but apart from the top part I don't think it conveys too well the "molten candle aspect": in my opinion the most of the melting should happen in a vertical motion while from the way you drew his skin he seems more pressed down than melted. The two droplets help in some way, but some more hints of "dripping" wouldn't hurt, especially on the skin nearer to the flame.
Another thing I noticed is the oversaturation of the yellow zone. It's great to have a focus point but imo it's a bit too much here, it's kind of weird to the point that more than a candle it seems like a yellow portal or an entire campfire on his head. I'd try to remove some of that brightness and use it to define more details up there, like a puddle of molten wax under the flame.
Lastly, the face near the eyes seems a bit flat, as if they were level with his forehead. Problably a bit of shadows wouldn't hurt there. Same thing near the two droplets.
Thumbs up man, keep it up.
