Greetings, Sissie 
Congrats on your candle spell! For reading candles and flames, my personal favorite is the Flickering Magick guide Francisco shared 
, and I can see Megan shared some additional amazing resources too 
As for reading candle wax, I can’t say I’m a wax-reading expert per say, but I do study a lot of magickal symbolism for my Tasseography readings and finding shapes in tea leaves is a similar method of divination to reading shapes in candle wax 
I’d be happy to give a reading a try, however, it’s a bit difficult to see shapes in these pictures- would you be able to show the candle from a bird’s eye (top down) point of view?
You could also give divining for shapes a try for yourself! I truly believe that the one who cast the candle spell will have the best interpretation, as you are the closest at heart to the issue and your personal readings will carry the most weight. Also, it may be easier than you think! 
The following guide was written for tea leaf readings, but can be applied to wax readings, cloud readings, crystal ball readings, and other various forms of divination too
A Brief Exercise to Finding Personal Symbol Interpretations
Peer into your teacup and use your creativity to pick out shapes.
When you see a shape– a dog, a circle, a cloud, an angry face, anything at all– what does it make you think of first? Does it bring back any important memories?
How does this image make you feel? Look at it closely to pick out any distinguishing traits– does it look happy, aggressive, sad, running away, etc?
And finally, how can this image relate to my intention/the question I asked for this reading?
Considering all of these points can help you find a meaning for everything that your tea leaves reveal for you!

Good luck and blessed be, Sissie!
