>>51001952The offset outline is really hard on the eyes, give the green more saturation and remove the offset. I'd also look for a pixel art grass texture and leaves to use in the corner for consistency. You literally have pixel art, a drawing, clip-art, and a photo all in one part of the image.
If you want you can use this leaf texture I made a while back as a divider, tile it as high as you need and rotate 45 degrees with Nearest Neighbor pixel blending to preserve the pixels.
