I started drawing this one yesterday and am hoping to have it finished this weekend. I also finally got back to work on FMC yesterday (which I'd started back around New Year's) and uploaded that one even though ArcCrypts recently uploaded an FMC, since it never hurts to have multiple takes on a tower (and my version shows the building entrances at street level) - plus I wanted to make sure I could upload and have the diagrams look right before I spend all the time drawing SLS.
Based on my FMC results, some of the SLS detailing will be lost when I convert my Illustrator vector-image file to a 1 pixel per meter gif file, but in SLS's case, that may not be such a bad thing since it's hard for me to get a good fix on some of the tower's details based on the few renderings that have been released - and since some of those details may change before the building is completed anyway.
But my SLS drawing should work as a decent placeholder until someone who's able to keep all their detail at the 1:1 GIF level (I'm guessing they're drawing raster images rather than vector images?) can tackle the job. Also, I'll include a request to update the building's height to 590' when I upload the drawing
