But to focus on the positives for a moment, so the thread isn't all negatives -
Matt & Chris look great; Chris looks mature and sensible if a bit dweeby, Matt looks like a kid trying to look cool - suits them both perfectly.
Amy's pose as she comes into the room is giving off cute vibes - even from the back I love it.
The dining room layout is different and presumably the rest of that space with the kitchen/living room is as well, I don't personally mind at all, go with what works for you.
The render overall looks great.
We hope to see more in future, keep up the great work
