Sagot :
I think they look great!
I like the angle, especially in the first photo, and your theme of flowers also looms with a theme of pink flowers, once again very pretty.
Did you edit all of them the same way, though, because it appears photos 2 and 3 are a little more unedited-? *I'm not criticizing, just asking :)*
Altogether you nailed the theme very nicely, and my advice is maybe to play around with brightness/exposure on 2 and 3 a bit more (if that's allowed, of course).
Good luck!

These look amazing, good lighting, angles, and good choice of flowers. However to continue in the nature side of things you could add photos such as animals, trees, skylines, and even trails of any kind. Personally I take my bike around to look for things like that but you can find beautiful things even in flowerpots or fields so pay attention for the beauty of things all around you outside. :)
