i will not comment on yout composition, neither the exposure.
concept wise the picture fails at first glance. 'Odd one out' ... obviously you're trying to say the mimosa flower/plant is the odd thing in the picture. i just see a mix of vegetation with a blooming mimosa flower, nothing odd about it, it's so natural. the theme needs context, the other plant which you want to contrast the mimosa plant against is too few and little to be considered as making a crowd such that the mimosa is odd.
