Beginner hobbyist. What do you think?

Hey there!

I recently found out how enjoyable making flower arrangements is. I have initially started using just flowers from Lidl but, this time, I have bought some flowers from the flower shop as well to "elevate" the look.

Do you guys have any constructive criticism on what I could improve? 🙌

Also, just curious how much could a bouquet like this sell for in your area?

Thank you!
