Well, I think you're giving Ted a bit too much credit there. It's not like he was the only person that could have made those translations and Square would have abandoned releasing those games in NA if he couldn't have done the job. Thank Square for wanting to release the games here int he first place. Thank Ted for doing the best he could in the stupidly short time frame he had to work with.
But I digress...
The sprites look much better in composition than the original sprites. And less be real, the old mobile/Steam sprites are not even in this competition. They're just hot garbage. Sorry, Mr. Intern. They have not aged well.
To get my
critique whining on, the new sprites do get a low score for the shading. It's the worst on Dark Knight Cecil's helmet where it's just straight up bad pillow shading. There is also a problem of palette choice like was already pointed out. Colors are a bit too saturated in the gradients. These are still pixel graphics so they need a good level of contrast or it will all kinda blend into a single color to your eye.
Still, it is a step in the right direction and nothing a simple color edit won't fix.
