^^^^ *Shakes head* Not true. This pose/angle is perfectly fine. (Although, perhaps a little boring/overdone) And it wouldn't be semi-realism style until you've gone down to an extreme worm's eye view + added huge boobs. heh.
As long as her head is looking up, it works. Once you shift it down (Like the redline) you break the impression you were going for. (Innocence/sadness) So follow the redline, but keep the angle of the head.
