critique wanted Should I readjust my light source or just call it done?

[3k932jd22328jdsf 113]

I originally shaded so the light source is coming from the sun above which isn't seen. After adding in the RainBoom I made its center a light source. Should I redo my shading for two light sources or leave it as is? And if I do shade for both light sources should I draw the diffusion of light coming from behind?

It's partially not my fault the colors are bad. I was using crayola colored pencils because I am in college and broke. What is a good brand for professional colored pencils?

I would shade the top of the hooves (in a dome shape) but other than that your art is on point! The light from behind looks amazing! Great job!
