@Jeanne-M-Bowman You're very good at drawing backgrounds, but it looks like your draw the whole neighborhood and then put the characters in it. That's actually backwards! At the planning stage, you decide where you characters will be and then design the background behind them in a way that won't interfere too much with reading them. Unlike with photography, you're not stuck working with reality. You can design the environment to suit your needs.
You have a very detailed house right behind your character, and that's really attracting attention but doesn't really need to be there. The houses left and right tell us already where we are, so in the middle you could just put a tree and suggest a less detailed house behind it, or even leave it empty. We still understand where we are The further away elements are, the less detailed they can be. Right now your background has a very high amount of details, and that does attract attention a bit too much. I would simplify a bit where that improves readability (for example, through the car window).
You can also push your filter much more to create depth and make this easier to read. It's too subtle right now. You can make it especially strong around the character to make him stand out.
Right behind the boy's face, I reduce the high contrast of the house's corner (which attracts too much attention) and covered up the 2 windows, opting for a simple brick texture to suggest a building. Then the tree and filter!
