Sorry! Next time I'll make sure to try harder to think up a better excuse. X-D :-P
Well, I wasn't planning on showing the back at all, as it was going to be filled in with red, but since I had enough grey, I filled it in with that. The reason I made the sides and the back solid, was I wanted it took look like this was just a segment of the dock, and it keeps going, but I guess the back looks a little strange as I put the back of the top wall on...
