A lot of users on Reddit think they are better than you. If they even sniff that you are promoting your own stuff, they'll vote it down to oblivion. I've been on Reddit for 9 years. I've gotten lots of views, but the big subreddits where you'll get the most action are almost impossible to penetrate. They seem to only want content that was found and not made by you. Each subreddit has a load of rules that you have to follow, so make sure you read them. You can't even post on /r/videos unless you have 10 karma in links and comments. Never hurts to try. Google how to make a good reddit post and you'll find lots of information. It can be very, very frustrating. And you'll be tempted to fight with the inane comments you may get. Good luck.
