Vision - I say it looks beautiful. The sun, the time of day and the roses make a good combo to enhance the beauty of the artwork. COMBO BREAKER!
PS: There's a bit of error with Cheerilees' eyes.
Originality - Haven't seen much artworks like these before, since this one looks original enough. The originality is high, despite using My Little Pony characters.
Technique - I can see you didn't copy-paste the roses. The Laziness Level for this artwork is 0.1. But I think the mass of roses close to Cheerilee, RD and Rose should be as sharp as them next time, and not too blurry though.
Impact - As I said in the Vision part, it's beautiful. It made me turn into a new man- no, I'm still straight, but this changed the meaning of beauty that my eyes seek. Since my favorite colors are red, brass and copper, this one has all the colors.
Overall - Mostly everything is good. The perspective, along with the colors, the dimensions, the lighting, the shading and other bunches of shit made this artwork a masterpiece and an epitome of composure to my eyes. Well done. May God be with you.
