Portfolio Dilemma

Hi everyone,
I have a slight dilemma putting my portfolio together. Basically, I have been working as an illustrator for a few years, with some authorial/editorial illustration work as well as stand alone drawings which I exhibit and sell, but recently have been focusing on learning 3D Game Art and building an prop/environments portfolio which I am still very new to. My illustration/drawing work is very different from the 3D work I have been making, and it's not really 3D or environment related, although in the distant future I would of course like to become good enough to merge the two disciplines and draw / model my own concepts.  At the moment I have an artstation separated into albums of 3D, Illustration and Drawing, but I wonder if I should have a separate website for illustration work and a separate one for 3D, or whether there is some benefit different disciplines as well?

Any input is greatly appreciated, thanks very much
