Your best bet is to ask Whiteflash what they think and/or whether they'd recommend alternatives. The ASET looks OK; whether the stone has enough fire is a question that can only be answered by looking at it in motion (video or eye).
ETA - I'm slow at posting today. If you look at how symmetrical the ASET image is, you should be reassured that there is nothing wrong with the symmetry in the "traditional" sense of the word. Also, you cannot judge a non-round ASET as you would assess a round. It is normal that there is a lot more green than red.
The table and culet point are pretty well aligned too. Also a GIA or AGS symmetry grade of "good" or above is a sign that there are no major mishaps in that sense.
The question I'd have is whether there is a feather that is being reflected. What clarity is the stone?
