For the front side of the postcard, I used a photo I took on vacation in the USVI and edited the exposure, saturation, contrast, tint, and so forth. After all that, I added a greeting text.
For the back side, I found a postcard template, then added text and inserted a small picture to fit the stamp box.
There’s not much of a story behind this. I’ve been replaying Kingdom Hearts the past few days with my friends, so it’s been stuck in my mind.
