She comes off as being very excited but not very practiced / experienced with the weapon. Not sure if that's just me or if anybody else is picking that up as well.
I would say the background is currently hurting your presentation. The weapon is difficult to read against the background because the colors and values are very similar.
Awesome resume'. I especially love the Hunter design and all the different concept iterations of the man, beast, and weapons. That is a lot of work. Keep it up!
The junction of the wooden butt and the metal trunk looks too clean. Also it is necessary to polish a little those places in which the shooter touches the weapon.
