"What the heck is Psychic Knife?!", you ask? It's Silver's attack from his rival battle in Sonic Generations

(if you had switched Omochao's hints off, you wouldn't know its name

)
Thinking about Silver's Psychic Knife attack being on par with Shadow's Chaos Spear inspired me to draw this

Many thanks to *
Tuskat sensei for teaching me about textures and layer modes

Now I don't have to worry about what background I should draw! WHEEEE

I wanted Shadow to be dodging Silver's Psychic Knife, but changed my mind and made him face the other way

Hooray for shooting Chaos Spears backwards like a boss

An alternate title for this is "The pic where the right arm/leg is left and the left arm/leg is right from the thumbnail"

Look at how tangled Silver's legs and Shadow's arms are!

Glad you like it
Seriously though this is beautiful, with very nice lighting, and the only thing is that yes Shadow's one arm is really... uh... well let's just say it could be better.
This is a bit off-topic, but when you did the lineart, what size and type of brush did you use? I don't use SAI but even on the rare occasions that I use Gimp I cannot for the life of me figure out how to make it look like that! Would you please tell me?
