Welcome to steemit! Good to see more photographers showing up here :)
I've been using steepshot to host my photos, it's an Instagram like platform that is linked directly to your steem blog. It's still in alpha and doesn't support markdown or HTML in the descriptions yet, so formatting is a bit tough. You can add formatting that will show up on steemit, but on steepshot just looks like a mess of characters. Plus you have 7 days to edit the post directly from your blog too.
So far all your photos are looking beautiful, keep it up! I look forward to seeing what else you have up your sleeve.
