To help revive this topic, I decided to post on what I'm working on. In fact, I started working on this mid-July, but I've had some bad luck with the laptop, and lost all the finished walking frames. But, I just finished them again today. So all that's left is the Falling, Hurt, Dead, Running/Floating, and Tails Pickup. And just like Espio, the heads were made by screenshots of a Silver model, taken by Senku. I also made him slightly lighter than Nitro's. Only 3 pixels lighter.
And while I'm at it, after it's finished, I'll add it to the Riders mod as well. When floating, he'll change into the floating frames, and I'm hoping to add a cool glowing effect for that, too. If OpenGL Shadows have been ported to Software mode already, then whenever he uses his ESP powers, he'll spawn a blue shadow that's slightly bigger than him. Just think of it as a normal Shield sprite, except that instead of Silver hiding behind it, the shield will be the one behing him. That way, it'll look like a glowing effect.
