Welcome to steem! There are quite a few teenagers here on the blockchain. There are a lot of contests you may want to look into for your photography. Try using tags like photocircle and photofeed. Also, if you take photos of dogs, there is a weekly contest called dogsofsteem. Good luck on the photos. Scott and I wanted to help you out by getting you some tips and tricks we learned over the past few months as new Steemians. You can view that post HERE

Also check out this Discord Server for new Steemians.
