My first ever set! Suggestions and feedback are welcome 🤠

Hi, I’m brand new to this but I made some Valentine’s themed cookies to mail to my friends! Since this was my first attempt at decorating I didn’t make my own icing, I just used the Betty Crocker cookie icing that comes in the little tube (definitely wasn’t the easiest to work with or control the flow of 🤷🏻‍♀️) I’m happy with them overall though! I would love any suggestions or advice, thanks! ☺️
