My Swing

I have been watching quite a few of my swing clips recently on V1 home swing software, where you can compare your swing to some pro swings. It makes it easy to see differences and faults. There is a list of thinks I would like to change about my swing:

Straightening of my right leg on the back swing.

Cupping of my left wrist at the top of the back swing, makes the club point slightly right at the top.

My wrists are far back behind my shoulder on the back swing, I.e. on a quite flat inside plane.

OTT move, possibly related to the swing plane.

Out to in, I don't release the club down the line, I release the club inside the line after impact.

I suspect there are other faults or issues that I don't have the knowledge to see yet.

The big question is, are any of these faults deal breakers with regards to improving over time? I still can't decide weather to tackle them now or leave them for the Autumn/winter/future and just concentrate on my short game now during the summer playing months while we have good greens conditions. My head say's get a short game, my heart wants a good full swing asap.

What I don't know is weather a good swing can help a consistent short game?

I can get around with my swing, (My best was just last night, 8 over par 66 for the 15 holes we played, but more often I score high 80's when I play well).

From videos it looks like I often aim slightly right (subconsciously, I don't do it on purpose), but I get a good release on the ball so I hit in effect a controlled pull which some times draws/hooks if I get it wrong, very occasionally I get a fade with a wood or long iron but that's rare, mostly my problem is the left side although recently while trying to deliberately swing in to out with driver and 3 wood I have been seeing more push shots than pulls.
