I think that the choice of background pretty much assures the status of 'snapshots' to these bubble-pix.
The inclusion of the finger and the reaching hand are wonderful elements but lost in significance amidst palings and shadowy murk.
Bubbles are a favourite symbol of many things: fragility, wonder, uniqueness, sparkle and, through cultural conditioning, aspiration.
To have shot these in a different space - perhaps against a blue sky - quite a strong metaphor could have been created. But alas .... a paling fence.
