2 pictures - 2 plants.

Hi

I would like to ask you how to shoot plants.
Please, give your comments about photo 1 and 2.

On the first picture you can see Helinathus bulbiferus.
On the second Echinops sphaerocephalus inside the wheat-field.

Are these photos good? What should be improved? Which is better?

I think more blue sky and less green stalks should be left on the first photo.
And what about second?

Thanks for all your comments
