That is just adorable, you did a great job.
But could I make a suggestion...... It looks like there is a cord at the bottom, if this is a cord through a casing you might want to consider substituting elastic for the cord.
I am a nurse and an EMT and a few years back we had a baby brought in to the ER who strangled itself on the tie cord of a sleeper while sleeping.
It's one of my soap boxes. Last year when I started knitting for my grandbaby I was really amazed to see so many patterns that incorporated ties. If you notice in stores, the baby clothes now use elastic at the bottom of sleepers and buntings.
