It's hard for me to say if they're good or not. Composition is, in my opinion, personal. I like the concept, and find your photos quite nice.

I've found that matching composition to my intended impression makes my photos stronger.

My wife finds my photos so-so, but others like them, so don't worry about it. Ask your mom how she thinks they could be better. You might find she likes them more if she's a bit involved.

Take care and have a great Thanksgiving!
