Reminds me of the Final Fantasy Gunblade, except more sophisticated.
Although I'm pretty sure that a weapon like this would not be very practical in a real-life setting, but it still looks awesome in a fictional setting nonetheless.
Wow, I never knew that there were gunblades like that in real life. Though I remember reading somewhere from an actual weapon designer that this sort of weapon would be a bit too difficult to wield, due to the location of the handle and trigger, and how it would suffer from other problems too. It might still be somewhat effective, but would be rather difficult to wield properly, and a rifle with a bayonet would be easier to use.
And a conceptual artist for Manga, Anime and Video games? That sounds cool, I wish you best of luck in that profession.
I have a lot of unique ideas too, but I can never come up with purely original ones, just fandom ones, and whenever I've had a purely original idea, it sucks overall. That's why I usually stick to fandom, and I'm pursuing a different profession for my dream of a life-long career.
