its cool you are trying to think of kicker endings, and using the same type of idea from 5 speed... but there are good ways to utilize a kicker ending and there are mediocre ways to utilize a kicker ending. No offense, in your case, it is a bit mediocre... mainly because, the way you presented the "freely chosen thought of card" was way too important, for you to just "toss it aside" in the beginning. It has a really staged feel to it. In 5 speed however, you can really pretend to lose the selected card and feel bad about it, then go into a completely different trick. I think it would be better to actually have them choose a card and you lose it into the deck, rather than just think of a card.
Secondly, you say "it would be cool if the card would end up in my pocket..." and at the end, it doesn't even do that when you produce it... thus you are setting the spectators up for something, but not delivering on it. Your words in the beginning kill the trick by not abiding to them.
Lastly... why do you cut the deck a few times after replacing the two of clubs into the middle of the deck... ? well, I know why you do it, but your spectators could think "why did he just cut the deck after putting it back into the middle... did he try to control it somewhere?" Spectators are getting smarter these days. Try to use a control "cherry? cascade? side steal" so that you can minimize your unecessary movements.
