Okay... the first effect - what was that about? It seemed like a transposition of a Joker and a selected card, but was convoluted with two other indifferent cards, a control that wasn't (and unnecessary, really) and some random dealing... the magic gets lost along the way, and isn't magical enough to warrant that much time spent on it. I recommend a classic two-card transposition utilising D/Ls - far more direct and natural.
The ones I currently use are
Peter Duffie's Crystal Clear Transpo and, for a lengthier effect, a Britland handling of Hamman's Signed Transversal Triplet with my own little twist at the end.
You need to work on your handling of the DL - it was apparent that there was more going on there than there should have been, and your handling after the change was more natural than before, which tips things a little bit (a Strike DL is a good, natural handling of it).
If you're going to do a mixture of the tent-vanish/DL then you might want to consider turning the cards so the back is towards the audience, the magic happens, then turn it back, still tented, to show the change.
The Erdnase was all right, but could be smoother and faster; it's just a matter of practice, but it's better if you don't push the card flush with the deck before it changes; keep it protruding as that happens. The pushing forward of the card should seem incidental, with no attention paid to it.
Can't fault the dropping of the cards

.
The next was the best, although your right hand could have been held a bit more naturally; the stiffness of it suggests something is going on there.
And yes, the last change flashed quite badly.
Apologies if that seemed overly-critical, that's just what came to me. Hope it's of some help!
