First Crit

Thanks for posting Andrew.

First off let me say that all opinions in this group are subjective and personal. All should be considered (and respected), but the final product needs to align with your own artistic vision and not that of others.
All should feel safe to express themselves, no opinion can be wrong.

Back to the subject. I really like what you have done here, I love the capture of birds on the feeder, and great tonal range.
If it were my own image (and again to suit my personal preferences) I would try the following;

1. Straighten up the window - the bottom and left especially are a little off (OK, so I'm a little anal....)
2. I think the image may lose something with the feeder being so central. I would suggest cropping the image, cutting out the left pane, and perhaps a little top & bottom until you feel the balance is right. I think that would create more balance (for me) and place more emphasis on the the birds/feeder .

Overall a wonderful image, I really hope to see more from you, and hope you'll feel comfortable engaging in other discussions.
