My Posts Are Getting Downvotes, Why? What Am I doing Wrong

I went through my post, and noticed some have a crap ton of down votes. I am not posting any spam, stolen content, I never copy other people's work. All photos are taken by me unless other wise noted. I post my YouTube videos to DTube, sometimes I embed the link. I am not breaking Steemits rules. SO why am I being down voted? This may hurt my repuation, and I am trying to save up my money so I can upgrade my YouTube equipment, I cannot do that if I am being down voted without a reason, if anyone knows why this is happening, or other things that can cause you to be down voted, PLEASE tell me in the comments so I know what to avoid/stop doing. It very upsetting that I am getting down voted and I have done nothing wrong ( as far as a know) so please help me.
