Awesome wax display, @SingingWitch! 
Did you ask any questions/have a focus while you were doing the wax spell/ritual? Knowing your intuition while casting will be important for finding the interpretation. Without knowing your intention I can only do a general reading.
With that in mind, here’s what I see…
(Note that the following correspondences are based on my own life experiences- others may have different interpretations that are also valid)
Crescent moon behind the clouds- a crescent moon is a phase of movement (either waning or waxing). As it is hiding behind the clouds, it may be that something is changing (either growing or shrinking) out of sight.
Swallow- a fast-paced bird that often appears to be dancing in the sky. It is a sign of good fortune, joy, and movement.
Seashell - a symbol of the ocean. May mean that something is hiding or being reclusive, although this may not be negative thing. I personally associate this type of shell with The Hermit card in Tarot- a time of meditation and isolation.
Just my thoughts for your consideration, @SingingWitch! 
As with any divination reading, I’m happy to share what I see, but I personally believe that the best and most accurate reading will always be done by whoever cast the spell- as their energies and intention where the one guiding it, and they are the closest to the situation being read for.
So when deciphering your wax reading, be confident and try to go with your gut instinct about what you see! 
Blessed be!
