The texture on the cape does look to be good but it's hard to know if it's an Obi Wan one from the picture. The arm holes fit the Jawa really snuggly so I'm not sure if it's a gap I'm seeing where it's a little loose or if that's just stretching from the cape.
Hard to say without some other pictures so it would be good to see more if possible but it does appear to be looking pretty good for it colour wise.
I don't have a VCJ for comparison but IMO looking at the listing this looks the real deal. Colour, length and pattern all appear correct, and Jawa itself is correct Coo.
