Im a beginner, what did i do wrong?

You overprocessed the asset. It has too much saturation and there is noise in the green. The out of focus parts are disturbing. The lower orangers suffer from the out of focus greens. Even that I think that there are optical reasons for this, they look like you would have applied a flattening filter. 

Looking just below the oranges, the green looks washed out, like you overprocessed to correct for under exposure.

It's oversaturated abd poorly composed, with those blurry branches obscuring parts of the frame.

Hello,

The out-of-focus branches I think are distracting. Especially, the one above the oranges.
