Hey @kina, welcome to the critique forum!
Very lovely! I like the simplicity in the photo – how well the flowers stand out in contrast to the dirt around them. And it does look better with that light brown spot edited out. There is another light brown spot at the top of the photo above the leftmost flower in the back – if you really want to get picky you could probably edit that out as well!
Compositionally, I notice that the bottoms of the leaves are cut off in the photo. One thing that @jamesstaddon said which helped me in a similar situation is that everything has “feet”, and they should be included in the photo. When you take a full-length portrait, you should include the subject’s feet, not have it cut off at their ankles. Same thing with flowers – if you’re including the full flower with the stem, include the “feet” – the bottom of the stem; if you’re taking a picture of a tree, include the “feet” – the base of the tree, etc. I hope that makes sense!
