megatronx, i think that's a very nice looking mockup. The layout and design in general are just about perfect, but the main banner image itself could use a little work. It's a little too large, and could use some tightening up on the design.
There are too many different styles of gears. The large one on the left is too skinny, and the one used as the C logo has some strange, sharp spurs on it. I'd also like to see a mix of newt's idea and yours, I think... having a series of Construct windows come out of the monitor would look great.
I might do a banner-image redesign based on your initial design, if it's all right with you
And — yeah, Lorem ipsum isn't Polish, it's Latin . It's commonly used as page filler for layout mockups.
