Avoiding an Evil Doctor

Beyond the horizon, Sora and Nicky entered a mechanical city after smashing a horde of badniks without any injury. The city had cool music, instrument stores, nightclubs, electronic shops and even those with accessories that vary from cowboy hats to bandanas. Suddenly, evil doctor Eggman came out of nowhere and went on a pursuit as the twins avoided him!
What is Eggman doing to his gigantic octopus mech?!

I haven't used Paint-friendly tools in Photoshop before, but I like how it turned out.
I redesigned Eggman by giving him a robe and making him more like Wario. I also gave the Octopusbot* (from Sonic Boom) a redesign, giving it a few mechanical spikes to make it more like Shadow.

*Octopusbot is from Sonic Boom
