Initial thoughts
Colour is lovely and strong, background is mostly a good bright white.
Composition/ Content
Content is interesting but it's not really obvious what one is looking at. The swirly paint "splat" doesn't seem to bear much relation to the neatly painted colour blocks inside the glass so it's not really clear that it's meant to be a spill of paint that was once in the glass. That said it's still interesting in a more abstract way.
Whilst I like the choice of a non-centred composition the choice here doesn't make for a particularly balanced frame to me. Perhaps having the "splat" further to the right might help? I'd also prefer the stem of the glass to be either more accurately vertical or tilted toward the top left corner.
Background
Mostly a good clean white but with some noisy grey smudges to the left side of the frame, both above and below the glass.
Technical
Focus on the glass seems OK though the stem seems a little soft. Exposure look good and colour is lovely and rich.
Fits The Challenge
How could it not?
My Opinion On The Photo
A nice image but not one that wows me or makes me want to look and look again. Partly because of the strange contradiction of neat painting inside the glass and very messy "splat". The splat also looks too artificial. Also partly because the composition just doesn't strike me as very balanced.
