We've been on the new layout for nearly 6 weeks. Our views have gone from about 50k per day to around 70k per day with a few days passing the 100k mark-but our sub level has also increased by 20k since we switched over, so that accounts for our increase in views more than anything else.
I took a look at your channel and where views are coming from. It looks like you got a decent percentage of views from Reddit. If you promoted a specific video, then numbers probably didn't change much, but if you promoted your channel, you don't have anything set to auto-play, so that could account for the drop in views.
