Using filters to turn full-colour illustrations into pixel art usually results in a sloppy final product.
But… it’s much less time intensive than drawing each sprite by hand. I’ve iterated on my automated Photoshop action many times, and it really fits the style I’m going for. In lieu of a budget and artists, it’s a good fallback.
I appreciate how the low fidelity of pixel art allows your imagination to fill in the details. Of course, my opinion is overwhelmingly coloured by nostalgia.
