Hi Amber. I'm in the same challenge and I'm looking forward to getting outside of my comfort zone on some of the challenges and hopefully growing as a photographer. I look forward to seeing your work throughout the year.
You will DEFINITELY grow as a photographer. I found the more uncomfortable I was with a challenge, the more I learned and grew as a photographer. My very first "levitation" challenge had me terrified for weeks because I had never done any advanced editing before. But, that one challenge more than any other probably made the most profound impact and taught me that just because something seems scary doesn't mean that it is and that it can't help you become better at what you love. My profile picture actually wound up as the album cover for "low key" week and I also got the album cover for "complementary colors" week. When I started the challenge I had never dreamed one of my pictures would be chosen as an album cover in such a large group of photographers, so to be chosen twice really boosted my confidence at the time and helped me to see how much I was learning and improving by participating.
Good luck! Find me in the group and reach out! I'd love to follow you and see your work as well!
