Is the improvement achieved by increasing the resolution or by blurring? In my opinion, it's better to approach the elements more selectively. Smooth details definitely look better, but in other respects, the detail has been lost, and the color palette has suffered. This is clearly visible on the hilt of the blade and especially on the unicorn. The blade and the font are much better perceived. I'm judging based on the screenshots.
