I love finding works of these two together. They are simply the best team and have such a unique relationship, and you captured that here. I like how you subtly suggested wings, but didn't actually the full-on alicorn route. The colors you chose rise up into the characters and set them apart at the same time. Well done!
Hmm... Is she a unicorn or an alicorn here? The thingies on the right ain't too clear about that. That said, it's one of my top favourites to be depicted, the bond between Twily and Spike. Just too lovely and adorable to pass by. Spike actually turned out the best here, both the expression and the overall body. Twi feels just a little bit too blurry. But yes, overall 's good.
Thanks for the comment. She suppose to be a unicorn. The wings thingies where suppose to look like wings, but at the same time they weren't, so yeah, I can sorta see why people might be a little so/so about that. I'm glad you thought it was cute since that was my biggest goal of this drawing.
