I love this and will have to find the stamp set to use yours as inspiration! The background paper echoing the balloons is really fun too.
About your comment that you’re a little more than a beginner but could do better? Inaccurate statement! ; ) You are tons more than a beginner, could teach beginners, and even Olympic athletes strive to be better.
ETA Ms. Enabler, I found the stamp - which was on sale for $3.94! (It showed up as more but when checking out a discount was applied.)
