Tech school needs to revamp its well known SVG background

Alura.com.br

We do provide online tech related courses like programming, web design and so on in Brazil. Our students are young, passionated who have just finished their graduation. 25 to 30 years old.

Nowadays, as you can see at http://www.alura.com.br, we have a light hearted SVG background with some buildings from around the world. It has a young and funny design. We have also modified it many times to celebrate different moments and dates:

We are looking for a new SVG that would be a little bit more serious, but still colorful and probably with a light/white background. It must have some buildings, technology and fun, but not as funny as before. We just lost our former designer and he was just doing this one. His latest try was the following, but it is just too dark and serious:

This must fit our new homepage, "Alura 2.0", that will feature not only our courses, but also our course paths and better CTAs:

Something like this if we would keep the old SVG background:

What we need you to do is to redesign the background SVG with the following:
- some buildings/skyline will make it related to our previous version. you are free to skip this idea but we think this way our students will be more comfortable with the new version
- one of the buildings should be a famous Brazilian landmark. for instance, you can google images for "museu masp sao paulo" and "ponte estaiada sao paulo"
- technology
- a small drone to keep the tradition and we will animate it
- fun/young but a little bit more serious than before
- any suggestions to make it closer to education/learning/work. maybe some buildings are still being built through technology
- the background color should be mainly white, but you can use some color
- the color palette should talk with the website that we already have. (take a look here for some suggestions:

What you need to deliver: the SVG background for the desktop version, and how to apply it to the homepage providing some space for 2-3 Call to actions at the left side.
