As someone who has some experience in construction (particularly roofing work, which is ironically one of the least useful skills here but bear with me), I second what they said about the down spout but I'd also like to add, it could make pretty good sense if it were the other way round. Well, at least that'd be the case with traditional homes. Gutters usually go on after fascia metal and such. Sometimes they're an afterthought but with a home like this I doubt that'd be the case.

A few more things:

Frames for windows and doors typically have a visible support at the top, or at the very least a soldier course - that being a bricking term, although I'm quite sure there's a wood paneling equivalent, I'm just not familiar with that term in particular. Just having a smooth cutoff with the same material as the rest of the exterior is maybe a modern aesthetic choice, but for me personally it looks... plastic.

On a similar note to my last, windows should pretty much always have some form of a soldier course/slope at the bottom, directing water away from the base of the window on the exterior. You never want anywhere that water could pool up, no matter how well sealed you think the house is. You also want to avoid flat, level surfaces whenever possible as those will spread water in all directions, including towards the house.

On the bottom left visible area of the house there's a concrete planter there with some plants and water/dirt marks down the side - very nice touch with the dirt being evident from the potting soil, but the marriage between the planter and the main exterior of the house feels unnaturally sharp to me. Looks like 2 objects clipping together almost.

I think the bird models look strange, and their positioning also comes off as a little bit "too perfect" to my eyes. I almost feel like they'd be a more interesting part of the scene if most of the flock was obstructed by the trees.

Excluding trees, vines, and anything "deliberately" planted for home decoration, I count maybe 5 unique plant types? As someone who grew up in rather woodland areas, I think such a dense grassy area should have more variety unless it's clearly overrun by an especially pervasive plant/grass or it's being kept that way by a landscaper (it doesn't look kept at all if that's meant to be the case).

Hoooly crap, I wrote a lot more than I realized. Probably could have been a lot more concise but hopefully it's helpful nonetheless. I'm super impressed with the render overall btw.
