@duffy44 Your investments are extremely diversified. I'd invest in an actively managed fund with good historic returns and low AUM, than so many investments.
Also, do you have insurance? It's quite important to have insurance in case life decides to fuck with you.
I understand that 3L is a savings account for your dad, but if your dad is not using it, have a realistic conversation with him about whether he really needs the money or not? 3L is enough to deal with most emergencies before deploying capital from other sources. You don't have to keep giving your dad 20k every month if he's not going to use it.
Also, 15k travel a month is extremely high for your salary, in my opinion. You might need to revaluate your spending habits.
The more you save now, the lesser debt you'll have to take, and the less pressure you'll be under for the repayment.
