I think that is Venus. Rotated image so north is at top and tried matching objects. Alas Mercury seems to be behind our planet.
Hey, you can see my house from there!
Well, La Palma anyway. Tenerife and Gran Canaria show up particularly well, likely because the former still has snow on Teide which fell from storm Therese whereas the latter, as the name suggests, is the biggest of the Canary Islands. El Roque, on La Palma, also has snow on it which is why La Palma is easily visible despite it being relatively small.
Incidentally, that storm dumped 419mm of rain on me which is about nine months typical rainfall. A significant amount came through the roof and ceiling. 8-(
