Started the final piece now still a bit rough at the moment, its starting to come together, the colouring still a bit smooth on the jumpsuit doesn't quite fit the hand drawn style i was going for right now but i still need  to do some more shading and then i can add a photocopy texture or a screen tone to it. the positioning still isn't quite right, think i need to change the perspective slightly. still need to draw a head crab and get it in the image. one thought that i had is that i need to have something on the other side of the portal, probably just an office or a lab i was also thinking about putting some marines or other scientist to illustrate what is goin on a little better.
