Reflection

Same as the exercise last week, we had to recolour b&w photos as well, although we had more choices this time around. This project was delayed quite a lot because I was finishing up assignments from other modules. Althought recolouring it didn't take too much time, I still ended up submitting this late (should rethink my time-manegment skills).
