Your character has turned out really well. Looking really great. Since this pose is a temp pose, only thing I can say is that the deformations in that pose looks pretty good. One thing I just noticed though, in your Tesse_15.jpg image, the tip of her shoes on the left leg has a concave curve. Maybe some technical issues with the rig?
As for the weapon, really nice textures and for the design wise, I have to say, I half agree with you XTitan. For one, this character is a robot, so even if the weapon looks over sized it shouldn’t affect her. Also, characters with unrealistic oversized weapons are not very uncommon in Japanese anime. After all, it’s all fantasy. The thing that I do agree with you though is the 2 hand aspects of it. I was just thinking how she would use the weapon with just 1 hand, and in my personal opinion, I think it’s going to look odd for her to not use her other hand when she does some special moves for instance. So the suggestion I have is to make the handle longer, enough room for her other hand.
Just out of curiousity, will you be playing with materials and the likes? Like making the weapon’s material metalic and what not and also will you be playing with special effects like adding electricity on her antennas like in your very first concept?
All in all, great job! Keep it up!
