First one I like, but I'm not too hot on the gaps to the right of the light... Just look a bit odd to me.
Second one.. Hmmm - think I prefer the pure light effect!
Third one ~ Cor! Loving this one. The composition is lovely, really makes it feel like you're peering in. The gaps around the light don't bother me here, oddly. I think because they're above it, it feels like it's sitting down on the floor - it feels more natural.
Really liking the mixture of opaque // transparent // in the middle marbles in this one though. It's just a lovely effect, and a lovely shot. Kudos to ye'
