Hello! Have you tried using a neural network to upscale icons from Heroes 3 and then retouching them with layers?
Good afternoon. I had one unsuccessful experience with neural networks; I tried to visually improve the Sword of Justice from Heroes 3... but it turned out even worse. So, I haven't tried doing that since. Mostly, I look for high-quality images online and then edit them in Photoshop (resizing, alpha channel, frame, outline).
