Fairy 1st Birthday cookies

Fairy 1st Birthday cookies (I'm still new to decorating with royal icing).
I had some icing consistency issues with the fairies and mushroom cookies. I thinned the icing out a little too much.
Each time I decorate, I like to try new techniques and learn new things. So, I did the grassy technique (that I saw on a post on social media) on the green cookie and it came out great. The color swipe with 2 shades of pink also came out the way I wanted. I got practice with transfers on the grassy cookie as well as the wand cookie. But at the end of the day, my grand daughters loved the cookies. And that makes me happy. Any constructive criticism/ideas for me? Be gentle, please! Thanks 🙂
