Double lunch time: The opener had a smooth, wushu-ish feeling to it. Your movements were kinda okay, but the first kick would have been a decap. Also, avoid rubbing uke around yourself just to dismember him.
Decap T 1: Wushu opener, not kinda good the second time around. The decap itself was nice, but you could have made it look more powerful. Also, work on a pose at the end. It makes things look cooler.
Headshot: Stiff opener, me no like. Smooth out your movements and make yourself move more fluidly.
Overall, considering that you are quite new to this, I suggest experimenting with your joints so that you can make a better opener.
