Thatchers Bridge

Just finished this jigsaw, top right has caused me grief, pieces just would not interlock so still not sure if it's right. Started a new 1000 piece of Endeavour in Whitby Harbour, this is a Gibson's and already I can see  the quality is superior. Extras wee Siskin Fledgeling, after crashing into window. This was the 3rd one in a few hours, bearing in mind I have bird stickers over most of patio window. They all eventually recovered and flew off, I stood guard against predators.  Freesias, I treated myself to.
