Nursery redecorate

Hi! I’m not part of the interior design group - im a graphic designer atm, but i love interior design too and i made a basic nursery a while ago and every day im not liking it more and more and im desperate to redecorate the room… im living in a rental so cant do much and really struggling with the layout as every wall has a different issue, if anyone has time and could pm me would love if you could give me ideas! thanks in advance!
