Looks cool, nice lightning.
The connection betwin the Barrel and the Base looks fragile and thin, I would make them more massive to bring it in line with the rest of the turret.
Ohh and I'm a bit dissapointed, You wrote "LARGE"and "MEGA" as Tags and then the turret is barely larger than my regular Capital turrets, No offence.
Just a "small" comparsion: Your "Mega god" turret vs my "God Spear Cannon" turret
