This looks awesome. This, in my opinion, must appeal a lot to kids. Because what kid wouldn't like to be picked up in the middle of the night by sorcerers that wear pointy hats and ride a massive dragon.
As for the piece itself, I loved how detailed the dragon looks, especially the scales. Same thing for the roof tiles. The color palette could've used a little more diversity, especially for things like the pigeons, that look unnatural (great job if this was intended).
The detail I liked the most was the orange cat just taking it all in. That definitely was the cherry on top.
Well done, and congrats on the DD.
