First floor looks real good. If you have kids perhaps a playroom aka future study for them.

Second floor.
1. Laundry room is fine, I have it in the same place in our plans near the master
2. What is the multi purpose room for? Have you considered it for the master and that way you can add an extra bedroom. Especially considering you have a finished basement.

I like a lot about the design-- the mudroom is great! I like the kitchen/great room a lot too. I think you like cleaning bathrooms more than I do, or you've got more help with it!

A small change I might make: reverse the stairs, so that the stairs leading down to the basement are closest to the front door (those are the stairs guests are most likely to use, right?) and rearrange the closet & bathroom of the front bedroom so that the laundry could be further from your bedroom. I say that because I'm sitting here in a room next to our laundry room listening to the spin cycle of our front loader.
