Robotails is REALLY well designed and drawn. And I love that the fireflies are still hanging around! The stylized background in the last panel is great too.
I almost used Tails-Doll, but chose not to because it just wasn't in keeping with how Roboticized animals looked in SatAM. Glad you liked my alternative design. ^_^
That's a great touch, the Robotnik looming with the roboticized Tails. Sonic's sarcasm really comes through in his expression in that second panel. Poor Tails...you nailed his emotions so well...
And emoting with Sonic characters is always a blast to draw for me; they've got these magnificent designs for expressing their feelings so clearly.
