I don’t think the house is too big compared to the kids - if that is the door on the right side I think it´s pretty accurate (the windows are way too big compared to the door, though).
There is an issue here that I see very often when people practice 2-point perspective: your vanishing points are too close. The general rule is that you cannot put vanishing points on the page with two points perspective (nor with three points). There are exceptions, but in general, your vanishing points should be further out to the right and left of the image if you want to avoid deformations. With digital tools, this is easy to manage. When I worked traditionally, I used to have a really large piece of cardboard to tape my paper on, so that I could set the vanishing points on the board to draw a perspective grid.
Another issue here is that the path is not in perspective. It doesn’t have the same vanishing point as the house, which is fine (it can be at an angle to it rather than parallel), but also it doesn’t actually have a left vanishing point (the sides are parallel), while it has a right vanishing point.
When you have objects that are not parallel, each has its own set of vanishing points, but the relationship between the „sets of vanishing points“ follows rules. It´s easier to keep everything parallel at the beginning, even thoug it looks stiff.
Here is a super trick for you. Take a photo that has the same perspective/viewpoint you want and create (trace) its perspective grid. You just need to look for two parallel „lines“ that are converging somewhere (roofline and line of the windows, for example) and trace them until you find the first vanishing point (and the horizon). Once you have the horizon, you only need one „line“ to find the other vanishing point. Once you have your horizon and vanishing points, delete the photo and just „fan out“ some random lines from both vanishing points: that´s your grid. You can use that to build your image and it will have correct „real-life“ perspective.
