All for the purpose of making us feel like a bird for a few moments. Another goal was to practice more with the 3D functions in Adobe Illustrator, and  in which these towers are made.  YNT SEOUL TOWER -  SEOUL”</span> </a>由 <a href="https://www.behance.net/coenpohl"><span style="font-size: 12px;color:black;">Coen Pohl</span></a> 授权许可 <span><a href="https://creativecommons.org/licenses/by-nc-nd/4.0/deed.zh" target="_blank" style="font-size: 12px;color:black;">Attribution-NoDerivs-NonCommercial 4.0 International<img src="" style="display: inline-block;height: 16px;width: auto;"></a></span></p>
