Going through your work I expected a whole different situation but your work honestly surprised me, I'm not a pro at all but I can see that your work has a level of proficiency that a lot of people find difficulty getting to.
In terms of style and sticking to it, my opinion is that we are made up of many things and have many influences, it's often implied that we must pick one thing and stick to it, but honestly, I think that's not necessary
I think it's okay to have a few styles to work in, to have different ways in which we express, render and illustrate
what you see as inconsistency, I see as variation
I'm not sure of what your situation is so I can't tell you what you should or must do,
But I don't personally think you will have much trouble getting work because of using a couple different styles of which they are all appealing and interesting to me!
your work is so cool and I can totally imagine it fitting into so many areas of professional careers !
