Necrozma Alternate Form - Speculation

I've noticed that other people have noticed that one of the new legendary Pokemon, Necrozma, kinda looks like a dragon's head. There's a bit of speculation that it might get an alternate dragon form in the next game. Here's my idea of what that form might look like. If there is one (since we didn't get a Z version back in Gen VI).

I've seen a few "leaks" featuring a Sugimori-style tracing of this drawing. If you know who originally traced it, please let me know. I've been keeping my eyes peeled for the source of the tracing since it was reported back in December. I need to ask the person to give credit, if they haven't done so already (and tell them they did a good job putting it in the official style).

On a related note, I think I'll call this form "Cosmic Necrozma" (roughly translated from the fake leaks).
