In need of a critique

[ChantalFournier]

I will be very brief and I'm sure others will have tons more advice. But consider what is important in your image. I would tend to think your two characters. Yet, they have the lowest constrast of all elements in the image. The spikes are way more contrasted and so are the luminous dots in the back. Attract our eyes to the important stuff, and consider the color of the light, everything looks very overcast right now, but I don't know if it's what you are looking for.
