English: A destructive/convergent plate margin/boundary with an oceanic plate subducting under another oceanic plate with a bit of continental crust. No labels, only arrows now, so it's language neutral, but someone may want to add them, or I might if I can be bothered to get round to it. A 3D orthogonal projection (at 10 degrees), 'flat colours' style, which I like the look of (and is easier for me to do).
