We will start by using these two images:
Step 1. Open the first image and paste the second one on top of it, using the blending mode: Lighten, 100%.
Step 2. Emphasize the colours of the image by applying successively three Selective Color layers, as follows:
The first layer:
Reds: -92 0 0 0
Cyans: -44 +100 0 -36
Blues: +100 -43 0 +25
Neutrals: -51 0 +100 +52The second layer:
Reds: -100 0 +100 0
Cyans: 0 0 -100 0
Blues: -57 0 -100 0
Neutrals: +25 0 -40 0The third layer:
Reds: -100 0 +100 0
Neutrals: +20 0 -20 0
To further emphasize the image, we will use a Curves adjustment:
Step 3. Now we will add the text. A handwriting font will always look great on this type of blend. I chose the font Carpenter, 130 pts, Color: white, without applying to it any further effects and wrote 'Summer bliss'. Then I duplicated the layer, moved it slightly upwards and changed its color to 5857fd (the color code is inserted here).
Another alternative for styling the text would have been (without duplicating the text layer) to go to Blending Options -> Stroke and add a 1 pt pink or orange outer border to it.
Step 4. Add a thick outer border to the final image by going to Image -> Canvas Size… and inserting the value 20 pixels for both Width and Height, and choosing the color white. Then go to the same menu again and choose 2 pixels for both Width and Height, and choose the color gray (notice that it will appear as orange because of the Selective Color layers).
The final result:
