I just realize you have been using a smartphone to take your photographs... That's impressive. These are stunning black-and-white photographs (I thought you took them with a DSLR).
Reflections can be quite challenging! Try photographing a glass Christmas ball... ha :D you will become frustrated, but it is a good exercise to find smart solutions! Thank you for the cup of coffee tribute, I just had a cup myself to start the day and the continue with the rest of the challenge ^^
