Spoiler:

I think it was almost impossible for her to have shot herself in that way and for her hands to end up in the position they were across her chest still holding the gun with not a splatter of blood. Actually even forgetting about the lack of blood, I'm sure there is no way her hands could have ended up in that position if she'd just shot herself in the forehead like that. The only little thing that makes it less professional i guess is that a professional killer would know that her positioning etc would look odd but that could be explained away by maybe he just rushed it at the end because of the security guy knocking on her door, him getting out of the locked door without a trace or a sighting though is pretty odd

Also, yes the teeth aging method was pretty crazy
