He probably really looks so sad because you are using elasticon tape on those ears. Is that what you are using? If so bad idea--very adhesive stretchy tape--intended for entirely different thing than ears but whatever you feel works for you.
But if you don't figure out a way to support that ear tip you'll have one heck of time trying to straighten it out later--even extending another section of rolled up tape could work but you can already see that they are bending --because your method basically is training them to do that.
Or you might be able to put a piece of mole foam cut to the shape of the ear tip extending down to below where the rolled tape stops--that would support the ear tip and shouldn't interfere with the rest of the posting.
