Hi Nico, good to have you here! I'm also pretty new on Steemit but happy to help if you have questions! You might already have discovered it but there are some regular photo contests run by Hive account@juliank and Hive account@czechglobalhosts. I'm not really a photographer so I haven't won anything yet but you seem to have a better chance :) And if not, it's still fun and a good way to connect... Have fun here.
