StH - Blackout Approaching

Sonic could swim once - long ago. But a terrible curse was placed upon him so that now he can only flounder, and sink like a rock to the bottom.
Once plunged into the liquid embrace, the Hedgehog can only slide downward through the water, as the air of the surface slips farther from his lungs' reach. He holds his breath to keep himself alive. But he can do this only so long.

Now however, it appears something has changed. The Hedgehog has perhaps found a way break this curse, or otherwise circumvent it, for he is buoyant again and floating along the surface. But, he has achieved this at what cost?

Soon the perfidous Tene from the darkest depths shall arrive to claim him. For in their treachery, they deceived Sonic, and what was promised to be a cure was instead an enslavement. The blackout is fast approaching...

OK, so this pic is a Milestone in my artistic career. It is THE 1ST pic I've ever drawn and colored completely on the computer. I've never done that before! 0.0
This isn't the first Sonic the Hedgehog pic I've drawn, but it is the first of them to get finished.
You like? I like!

NOTE: Title comes from an Imogen Heap song... "Glittering Cloud"
