Blackpink concert in Bangkok

Hello everyone. Is anyone who has concert experience of floor seating in Rajamangala stadium in Bangkok? I got a Blackpink Deadline concert ticket there. And my seat is in B7. And I'm really worrying about will not seeing anything. My height is 4'9/150cm. If everyone stood up, I couldn't see anything?

And I got my tickets from a pre-sale with my membership. My thaiticketmajor profile matches with my passport and weverse account.  But I was really panicked when I tried to get tickets, and I think there was a section where I should write my name and I only wrote my given name without my last name. /got 2 ticket one is for my friend and I also wrote only her given name because I didn't know her last name/ Is this going to be a problem or can I go to the stadium because my passport, weverse and thaiticketmajor account name are matching. And this is going to be my first ever kpop concert and solo trip from Mongolia. /My friend will not be going with me together/ So right now, I'm really worrying about everything about this experience. Am I worrying too much? Everything will be okay, right? Please give me advice.
