I wouldn't say you are getting a lot of views... the views to subscriber ratio actually look quite fair in my personal opinion. Check the data and see how many subscribers are watchers and then check your retention data to see if people are just clicking off.
I've got a pretty nice collection of mics that I use depending on the shoot although I don't currently own an XLR shotgun as I haven't needed one yet. I suppose its something I should likely look at as well though...
I'm looking at picking up a few Aputure 120D Mark 2 lights in the near future... I also may pick up a second lapel mic.
I'm very on the fence about picking up the new Pocket Cinema Camera 6k due to reports of a cheap feeling chassis but its possible I'll still pick one up to be a B-Cam.
