Dale you read my last post on another thread to Phil about owls and time in the field never wasted. What you are doing with the hide is no different to the owls or your kingies or my hares. That might sound weird......................... on the surface tis a total opposite.
Tis the same mate because of the repetition and the learning curve that goes with that .
Bro clean bkgs and birdz an beasti portraits .......................... You asked too clean and for me yup.

Mate I'm coming to realize I love that separation that the shallow dof gives. But if my BKG is really clean really uniform ,I sort of feel I have lost something. I can sort of compensate with foreground with a ground dweller ,but with a bird its harder.
Mate this is very personal it's not really critique of your images at all............... just where all this is taking me I guess. So thoughts mate no more:
If my BKG is as clean as yours above, I often feel I've sort of missed a chance to of tell a story to my viewer.............. the bkg................ even if utterly OOF can hold shapes tones colour that give clues.... hints that might, ha MIGHT, make an image more involving. You control these BKG's in this senario Dale so yeah............ too clean .
Too clean on the goldie bro the siskin has more for me not enough but more
.
You have done all the graft explore the bkgs how can you enhance what you've earnt I think you need some props mate

............ say Alder cones for the siskins ha the oh so obvious teasels for goldies but maybe work depth into that so the impression for me your viewer is i'm seeing a flock of goldies feeding in a field of teasels not a bird on a stem or a siskin feeding in nature. only I'm at eye level with it top of an alder tree
Mate it's a hide you are sort of creating a still's............ movie set,. for wild things which is cool . you have a degree of control and I think that could be better explored
I ain't ever going to see a goldie shouting at another on a bit of oak. am I mate you know this

Neither of us is ever going to bumble into that situation.
But we might see them squabbling over some thistles or dandelions or. ok teasels
Huge potential here buddy I don't know personally where you can improve bar telling a better story within the image
fair play mate !!
