I think we both started with the massing studies and looked at the lines on these massing models. They do have a measure on them also, which is important for 3D modeling that can be used with the height and the elevation drawings to find more measurements. The renderings in the skyline, as M.K. said, show more curves and the second model used these curves. I also had similar numbers originally, but did find some of the actual numbers and made the second version closer to those numbers. It wasn't a number divisible by 10 or 5, but was greater than 20 along the top. I experimented with new rendering software, but used my old rendering software for the final and the image below. I also wanted to see it with greater transparency and an internal structure, but the greater transparency looked fake and an internal structure increases the polygon count dramatically. I rendered one view and didn't add any clouds, then added some clouds along the side and then layered five layers over the original model render to add more realism to the clouds and light effects. I finished with drawing additional details on the fins and trying to make the window details stand-out more.
