There are very few Digimon walls in the gallery, and none that feature Yamato
-->hence this wall.

I vectored the original screenshot:

The tricky part was reconstructing the top portion of Yamato's hair.

After reviewing older comments, I got rid of the old cloud, sky, sun ray bg and instead used various tuts to create an abstract sun ray/light burst bg pattern, and tweeked it up a bit to make it more abstract.

I added grunge brushes and grunge texture to help dirty up the wall and give it a more rebellious/punk feel (to emulate Yamato's personality).

I keep the color scheme blue (from Yamato's eyes), grey, and black (found in Yamato's shirt) to keep the "cool" feel of the wall and the quote was from season 1.

Since Yamato has such a surprised look, I envisioned him being chased by fan girls (which makes the quote fit).

EDIT: I omitted the blue text on the borders, and integrated Yamato's phrase into the "wordle" in the actual wall...

EDIT: Removed the black borders since the majority of critiques felt borders were not doing justice to the wall.
