several mistake

the image you posted has extra transparent pixels on bottom and left, while losing a few pixels at top and right

the two 'clean' images are using low bit depth for some reason (looks like 256 color indexed?). this leads to dithering artifacts that aren't there in the source material.

since both images have been downconverted to lower bit depth individually, they're using slightly different colors around the seam

also you misaligned the images by 1px on the seam; the source images fit perfectly but you moved them closer by a pixel so they don't

fortunately, the image you were trying to create already exists without those mistakes here http://kachagain.com/llsif/pairs/angel.png

pic related shows diff; you can see misalignment on left side and the dithering noise on the right (a perfect match would be all grey). upscaled 2x so you can see the dithering
