Lara Croft, shooting 3 fingers under?

Is Lara Croft shooting with 3 fingers under the arrow? Or is it just really bad CGI? The arrow seems to be lined up in an odd way.

Attention Tomb Raider producers...

While we are excited to see more archery oriented films being made, what we don't need is more bad CGI of actors who apparently don't know how to shoot.

Below is the movie trailer... Hopefully they do a decent job, but the above image makes you wonder if it will be horribly inaccurate.
