Nice catch to find this orange tree. I think the composition is perhaps too central and too far away. I think by getting in closer and trying other angles you could have filled the frame with more intersting elements and less of the sky/ground.
Not too sure why you only went up to 510 pixels on this...
More interest could have been added to the subject by taking your photo closer and at an angle of some sort to make it seem more tremendous or towering.
