Unless the little guy receiving your quilt is a baby, I would consider making it bigger so that it fits on his "big boy" bed. He's gonna love this quilt for LOTS of years!
I made a Thomas the Train crib quilt for our grandson, and then had to figure out how to make it bigger when he outgrew the crib.
Be sure that you have enough matching/coordinating fabric to enlarge it later if you decide it's big enough now.
JMHO Great Job!!!
