Sounds neat!
Here are some tips:
Try to make the story as unique as possible. A lot of us have already played the games and aren't particularly amused by reused dialogue/plot elements as we are unique ones. Perhaps some Blockheads broke into Aperture to steal their technology or something. Just an idea.
Your logo is a little bit out of proportion. It looks like you were trying to copy some pixel art or something - I could be wrong. As plates are rectangular, that'll happen. You might be able to fix the problem by using stacks of 2 1x1s as your base "pixel."
If you are planning on including some test chambers, you can make a pretty slick setup really fast with just some default wall bricks and one or two printplate add-ons. The Portal Gun mod isn't perfect, so make sure to think big when designing the map (you don't want anyone accidentally touching a random portal).
In regards to the second image, try limiting the amount of bricks you include in the walls; they're unnecessary. You could probably make a kickin' one with some 1x4x2s. Oh, and you wrote "innovators" wrong. No biggie! Simple mistake. Happens all the time. :p
Maybe try messing with the light a little? I think your whites could be a bit brighter - you know, really make 'em pop.
Ooh, and maybe add some officey kinda' stuff. Perhaps some vents to explore.
Additionally, instead of attaching one image to one post as you've been doing, you can upload your images to an an image hosting website such as
imgur and include
multiple images in a
single post. To do this (with imgur), go to imgur, select "upload images" at the top of the screen, follow the instructions, and when the images are done, copy the text in the "BBCode (message boards & forums)" box and paste it into your post. You can have as many as you want!
Keep up the good work, Servo.
We're looking forward to see what you can create. <3
