Feeling the Winter Blues - so why not get help on what I should work on during the offseason?

I'm just curious to know whose golf swing I should replicate since I can't tell who I swing like.

Other than that any tips or advice will help. The things I always work on with this club is tempo, swinging up, full shoulder rotation, balance and setup if that's not enough.

Video angles aren't probably the best to analyze mechanics but I thought they were decent swings.

These were the last swings I took of 2016 and have not played in 2 weeks prior to this so it's my most natural and not necessarily the sharpest.

Not sure how to increase video quality but they are watchable. Thanks.
