Are my car detailing expectations too high?

Got my car detailed today. It was $300 for interior only. There are several spots that are still not clean. I wanted the car to look close to new. Here are some pics that show where there is still a mess. Is this normal or did they do a poor job? If they did a poor job how should I tell them that?

My son (8) did a better job in 1h30min for 3€ last weekend.

Pay him a proper amount so he's motivated to do it again, and he doesn't grow up selling himself short.
