Help needed. I’m a little desperate.

My stepdaughter has asked me to make a cake for my granddaughter’s 5th birthday. I made her 4th birthday cake (the picture above). I know my stepdaughter was disappointed in it, and I was a little, too. I wish I could have done better. My stepdaughter really wants something she can post pictures of, and I know she’s only asking me because she doesn’t have the money to buy something nice. I love baking and I want to do better. What can I do? I’m grateful for any and all advice.
