Feel free to be brutal if you hate the idea haha

We've had it picked out for probably 2 years and we both like the idea, but now that I'm getting ready to buy a lot of the stuff I'm second guessing it!! The walls would be light grey, with white blinds and maybe a colored (green or purple sheer) curtains over top. All of our furniture will be espresso. We already have a changing table/dressor from when i was a baby that we have to paint. These are some of the things we have picked out. (The owl is a room thermometer, the turtle plays lullabies, and the elephant is a dehumidifier)

I'm honestly terrible at decorating and planning things to actually match lol so I'd really appreciate any feedback or ideas on this so that this nursery doesn't end up awful!!
