Nice,but imho should have a lot more contrast.
In IR i try and get the Blue sky as a black

H`mm
Composition is spot on,thirds all the way,power station just off center.
Exposure--depends what your after.This works fine and its a good "as is" shot. A longer exposure would give you more light ppossibly bringing out the yellows in the field.This would also "stretch the clouds" which a lot of people like.
To keep the clouds as is a NG filter might be used to bring down the light from the sky allowing to balance the flowers--or my prefered methord, take your meter reading from the sky,then from the field then meet half way .
Focus about a 1/3 into image and set to area focus.(always use manual focus on camera and lens)
My way isn`t neccesarilly correct,just the way i do it,works for me

Good depth of field in the image.Nice detail in body and legs however a little blown out on the leaves.
I find the image a bit flat on full frame almost like a tight crop,however it has a lot of merit in the detail .
A Monopod is a must for these shots to keep them pin sharp.Some people take several shots at diferant focus points,stack the images and then rub out the any soft areas. Maybe a slightly longer lens might help (we can`t own the whole range so well do for maxamising your 150mm)
Hope this helps and still well worthy of a click

Ahhh here we go again,how to put my big foot right in it.
Composition is spot on,
Shutter speed spot on,
I like the one post breaking the minimal horizon
Colours---imho---and that don`t count for much--are a little too strong (Bending a bit towards chocolate box and the viewer)

Mute the colour down and i`d give it two votes!

Nice classical framing.Nice shot.
I may of prefered the camera to be a tad over to the left so as to use the gate as a lead in,allowing more of the field(and light) to be in view.As it is the image stops at the gate and then picks up again at the clouds.
Hope this helps.
