This picture by far is amazing and captivating, the colors, the background, the highlights and shades, you are amazing at eyes, and you can tell you take pride in your pony artwork. I love the way you color, the shiny aspect of it makes me know it's your art. I can't do backgrounds so you get a thumbs up on that, and that moon looks so cool.
I have a problem with where the umbrella's shade hits because the light it coming from what seems like the moon so the shade would sit in front of the stallion, not the block. I also want to know what is the block and the little patch of grass, is the block making the grass, that isn't well explained. The ground looks smooth yet rigid, I personally would of added a bit of texture there just for looks.
Once again with the background, the sky is just amazing, the colors look great and overall that is where the impact is. You did an amazing job, congrats on your coloring skills.
