It's a full scratch. The only thing from other sprites that are in there are the colors.
If you don't believe me, here's the outline before I started coloring it. It's not my fault Twash gave me a picture of a Groudon/Snorlax fusion.
And for the record, none of the sprites I showcase here on Smogon or DeviantArt use parts from other sprites. Ever. I don't do fusions, and I don't do recolors. I scratch. When I borrow a pose, I scratch it out, and when I do a revamp, I scratch it out. Every sprite I make starts on a blank, white background, without ever touching Ctrl+V.
