not bad at all.
vanishing key-performed quite nicely, just looked a bit stiff.
appearing note-this is a cool effect. but you need to relax more, and there is to much movement of the cards. just show that there is nothing on the back and front of both cards, and smoothly produce the note.
kings-that could be a great trick with the right patter or a funny story line.
jumping coin-this is a great effect. i find it hard to do with out a table, i need to practice it more. again could be better with patter.
magic-i dont have much to say for this. except a few false shuffles would have made it more convincing.
all in all not bad for your first videos. a couple of tips-angle the camera to yourself not you to it.use patter

it makes a world of difference and practice the handling of the cards more (especially your d.l) you look to stiff.
very good
