Can anyone give me feedback about these pictures ?

You are getting close to the quality you want. Perhaps still worth working on color

I was there 47+ years ago on my honeymoon it was winter and I was dressed warmer. Loved the cave room in the castle and the dragon banister in the tower stairwell  and thought it ball room was quite large. I did not need to be composite into the image. However the images are just memories now. The castle in the background is his farther's the swan castle.

If that is Auckland I was the in 2003 after I retired I looked older than If its Toronto I can not remember when I was there the Tower also look like one on the Canadian side of Niagara falls all towers seem to look alike in my memories except of course tower Eiffel.

Hi cathrinen92883330,

You are getting close to the quality you want. The couple is suffering exposure problems while the backgrounds look good. Keep the inserted couple on its own level and adjust the exposure to make the couple look as clear, bright and tight focus as the background. Do not merge layers until these corrections to the couple are not just good but GREAT!. Tip: Careful not to overdo the post-production work. The last photo is too blurry and so you do not need to blur the couple too. Sharpen them and drop them into a misty background if you like but blurs are often rejected by Adobe Stock. Best regards, JH

Hi

I like the last one the best but - they must be vampires ! No reflection of the couple in the floor

The second one needs some lighting glow on the edge of the couple to make it fit with the backlighting.

In general terms, when compositing look at :

1. Matching perspective

2. Matching lighting - i.e. direction and colour and also saturation

3. Matching shadows - look at the shadows from the leaves in the first pic.(down and slightly to the right) so why is there a shadow to the left of the couple?

4. Matching sharpness - sometimes that means introducting a little blur around the edge to make something "sit"

I hope that helps

Dave
