Dirty Mug - Blending in Blender practice

Somehow I missed legendary Blender tutorial for mug creation and photo blending, so I decided to spend some time and get new skills. Never did something like that before in Blender. But normal mug and photo was not so exciting for me, so I changed it to my shitty photo of my kitchen's table with New Year leftovers. And for that reason I did mug dirty too. The most challenging thing here for me was to match final render with original photo shitty quality. Everything done in Blender.
