For this effect to be truly magical it require that the spectator (unconsciously) is convinced that:
The chosen card could be any card (this should be easy to achieve in this effect, however since the second choice is a force, you should try to find a method of selecting the first card, that help "mask" that the second choice is a force).
Your way of putting the card back in the pack looks weird! Certainly, since you are to tense and look at the cards. The way to place back the card in the pack should be without suspicion. From the clips it appears you somehow pay attention to the pack and "are doing something". I suggest that you first "establish" the Hindu shuffle as the way you shuffle the cards. By some practice you should be able to do this relaxed and on the off beat.
Your D/L is a disaster! Sorry, to say this. It is crucial for this effect to be genuinely magical that the D/L is very clean. I am not claiming that I have the perfect D/L (I do not), the way you display the two cards are not natural. I suggest you find a way to prepare for the D/L while looking at the spectator! Again on the offbeat. It is OK they are "burning" your hands but not while fumbling to find the two cards.
I suggest you also use one of a number of subtleties of displaying the spectators card in a way that the lay person (unconsciously) are convinced that there is only one card! Of course you are only holding one card

, but a lay person might get the absurd idea that you in fact are holding two or more cards. Of course magicians would never do such an unfair thing, but how can the layperson know that???
The giveaway is very bad for a number of reasons!
If the spectator get the impression that you might be displaying two cards as one the magic goes down the drain!
Anyway red-hot mamma is a really nice effect even though some magicians might argue that its boils down to a very elaborate colour change that get obscured by the 51 other cards!!
With the shuffling and right card handling I think the effect - for the layperson - might become MORE magical than a colour change of a single card!!
The first brain wave effect should only be performed ONCE! By repeating it you are essential giving away that the method somehow is related to “fishy display” of the cards. Of course, serious magicians would never do such a thing as not displaying the cards in a genuine fashion, but how would the layperson know this??
