Thank you for your analysis, the poem is a follow-up. If the feeling wasn't caught at first, I wanted it to help the value I placed on the drawing.
The border is yes and no intentional, there were a lot more lines illustrating the trees in the beta design, but I opted for a dark border, so I can illustrate the light from the lake.
The combinations were something that just worked, I made the characters with more detail so that it would be easier to notice them. But when I finished placing them in the scene I was sure that now all that was left was the rest of the pixel art.
