I do like this, but I think the picture of the earth is a little too complicated. If it had been a simple shape or something similar it should have looked better. Looking at the droplets there is too much to see in them.
I always love water drops, and this is an interesting shot indeed to put the earth behind glass. I see some marks in the glass over toward the right that are a tiny bit distracting though. It would be nice if the entire background was black, I think. I see the gradient does help the water drops. I am conflicted. Something needs to change, but I think it's in the background.
Interesting alternative to a seemingly site favourite effect-type shot... using a picture of the earth is a good idea - however, the droplets don't to me appear large or frequent enough to have a great startling impact. the image of the earth is very clear - i initially thought the place you'd never been before was outer space! overall, the concept is good, the actual carrying out not as WOW as it might have been... 5.
I'm assuming you're not submitting these images from the space station, so how did you pull this off. Is it a photo of a photo. Anyway, it's a creative solution to the problem of the challenge.
I think this is a really good photo. I think the water droplets are a bit overdone in all challenges - there seems to be one or two photos that uses this effect so you may find your marks suffer. However, I do like it in this instance.
