For me, I wish the letter size on your header were larger and perhaps force justified along the length of the photo. I think it would give your poster a greater impact overall. I liike the green border. Good color choice.
well composed shot, might need a boost in contrast and sharpness. image and text go very well together, nice color scheme. Wish you had used a less worn out typeface, a bigger font size for the headline and a smaller one for the author.
