The pink and purple invasion has calmed down a bit, although still pretty prominent in the main area.
I like the idea of the grass and other elements of the main house area being pink/purple/magenta, it reminds me of some of the zombie environments from PVZ: Garden Warfare 2. Compared to the buildings in the background, I could already tell the main house is going to be one of those things where it sticks out so much from the rest of the environment (like Gru's house in Despicable Me, or every "wE nEeD tO fInD tHe ViLlAiN's LaIr!" thing. It could work on multiple accounts and I like that idea.)
The sky is great, but the house still feels kind of scuffed. It's probably because of the lines that form the bricks of the house, but that's just my perspective. Either way, it's clear you're experimenting with the environment of the house, and it's good to see you try out some designs to see which environment fits the house more. You're doing good Mr. Mania.
(I swear I'll be angered to oblivion if your favorite color isn't purple or pink in spite of everything related to the show so far.)

The mellow blue color of the sky really makes the house stand out. I really like it.
