I have this image in Photoshop where the background is one layer and the phone and hand is the 2nd layer. So there are two layers:
Right now the hand and phone look kinda of like separate from the background, I want it to be more smooth around the edges, I tried using feather but this didn't work. Any tips or a way to make it look more smooth would be great.
The edges aren't the main problem. The color balance between the foreground and the background images are off. The hand and phone are more "cool" or "blue" compared to the background image, which is very warm (yellow).
Play with the colors in the foreground to more closely match the background colors.
Then there may be an issue with the lighting in the foreground not matching the background, but it's hard for me to tell.
