Seamless Cabin Poster Touch-Up

I have three files for you:
• “Cabin Poster Images” – the individual pictures
• “Cabin Poster Crude Edit” – my rough layout
• “Cabin Poster” – the polished look I’m aiming for

Your job is to copy-paste the images into the rough layout and blend the seams so the final piece matches the smooth, unified feel of the reference poster. No text needs to be added or changed. Please match the overall color tone across photos; brightness and contrast are already close enough.

Use any software you prefer—Photoshop, GIMP, or another tool is fine—as long as the result is clean and delivered in:
1. A high-resolution flattened PDF or PNG ready for print
2. (If you work in layers) an editable source file for future tweaks

Timing is critical. I will award the project around 9:00 am New York time on Thursday, October 9 and need the finished files uploaded no later than 4:00 pm the same day. This is a quick, straightforward touch-up, so please only bid if you can start immediately upon selection and hit the deadline.
