This are the screenshots of the characters I used to combined together into an image. I used magic tool to delete the background which was challenging because I needed to understand the best number of tolerance to use to capture the lines of the characters.

This is the result I got.
I think I understand more about blending mode which I used for the background to find a perfect match that fits with everything.
