This is an attractive photo. The glare from the candle's flame detracts from it a bit - overwhelms that section of the photo - and I wonder if you might have been able to tone that down partly somehow. A slower exposure might well have made the lower ice cubes too dim to see as clear detail (and the amount of detail in the middle layer is really nice). Possibly partly obscuring the flame behind an ice cube would help, but it might also have made it worse - I don't know if you tried these.
At any rate, while I think that could improve it if some way could be found to do it at all, it's still a lovely photo as-is.
This is a nice abstract type of picture. I like it but it's not compelling. I really like the idea of this, and I'm not sure what I would have done differently, but it seems to need something. Now that I look at it a little longer, I realize I'm not seeing any drips to indicate melt down. Perhaps that is all it really needs.
Darn, why didn't I think of that? I was going though tea-light and ice combinations in my mind's eye... but you've done a much better job than I would have done! The black background is great, and you have successfully managed to avoid the usual noise that a photo like this in low light would typically generate. My one criticism is that I don't like the colour of the ice here... it looks a bit dirty yellow, perhaps a colour balance on the highlights might have done the trick (perhaps a slight shift to blue), or perhaps a bit of desaturation on yellow. 8
