Caleb, I agree with Rusty, I think that you are very, very close, if not already there at the Level II riding standard. There are some very minor things that I would brush up but it looks like you are more than well on your way.
I will sum my feedback on your riding in 3 words: EARLIER TAIL PRESSURE.
1. You pick up the tail of your board, rather than driving the edge through the entire arc of the turn ... said another way, you ride the board slightly too fore for too long. If I were to focus on one thing, it'd be this. I can totally see an examiner pinch you for this because the visual is so clear. The things below, I bet you can shmooze and get away with.
2. Toeside is snappier than heelside. This is a function of 1)
3. I might close my turns more for an examiner in to a full C. Some of them are pretty picky about this. I think you have the move, and this more of an exam tactics thing IMHO. A full closed traversed C will really expose the challenges in your riding.
4. You linking 180 toe-to-toes come off more as nose roll-ish than a nice clean 180 - which is related to earlier tail pressure too if you can believe it.
1. :05 - :15 on the "2013 mix"- See how you pick up the tail of your board (:08 is very pronounced, 1:22 shows it too) and move it uphill and pivot off your front foot. As you progress, examiners are going to want to see that the tail of the board can closely match the nose of the board on short snappies on intermediate terrain.
2&3. 1:19 - 1:23 - Watch the difference between the snap and where the snow flies off your edge. Toeside, its early and flying out at the 3 o'clock direction. Heelside, more like the 7-8 o'clock area. Why? Your tail edge engagement is better toeside even with your little "pick me up" move.
4. On Keystone at 2:58 during your 180 segment:
a) Watch where you pop. It is on the front part of the board rather than toward the center (again earlier tail pressure, it's all related).
b) Let your shoulders turn with the board. Freeze the video when you are landing and you will see that you are counter-rotated and blocking yourself.
c) As soon as you pop, you need to collapse more on the new front leg - think about moving your weight along the board to the new, switch nose, and collapse ... hard.
You know you have this dialed when you can jam that toe side edge in on both sides and make clean interlocking C's in the snow with no wash ... then try heel to heel!
(Believe it or not -- I actually taught this 180 segment during my LII, I even taught it in my level III - but we did it in the bumps)
Two good drills for 1-3:
Snappy power garlands - think as you are setting up the turn to try and "scootch" your board forward to engage the tail sooner. You can practice this move as a garland/traverse. Imagine you are coming across on your toe edge and as you halfway transition to a flat base in the fall line, slide the board down the hill, and engage the toe side edge again. When you do this move right, you will feel a bite on the board and the tail snap. Try the heel side as well. Once you master that and feel it, take it to your regular turns and play with where you can initiate that move in the turn shape (the earlier the better!)
Half-ollie turns - Lift the nose of your board in the transition of each turn across the fall line, a half-ollie ... you can only do this if you are engaging the tail. The collapse on to the new edge downhill
Again, I think that you are very strong and very close. I hope that this helps!
Remember -- EARLIER TAIL PRESSURE!
