Go back again to the past, but this time, for the human sake

In a fictional world for the year 2021, Doc and Marty find it necessary to help the WHO to recover the studies and satisfactory results of the only successful vaccine against the disease that humanity faced. Before leaving, the disease had killed just over half of humanity. A terrorist organization with inexplicable plans for human understanding had destroyed all the laboratories and servers that contained all the information on the investigations and results of the vaccine. Before the WHO made the event public, Doc and Marty were already contacted urgently by Marty's own daughter, Marlene, who worked as a biochemist in one of the laboratories and managed to get out alive but not injured in the terrorist attack.

All this work I did only with blender, on a laptop without a graphics card with an AMD A6 micro from 2013 and 4gb of Ram and using only the keyboard and the touchpad of the laptop. I know you will wonder why I do it like that but I have my reasons. Honestly, I was almost on the point of not continuing to participate in the challenge, I had many problems that sabotaged me, my laptop gave problems, I lost things that I had to do again, the smoke that is not seen in the clay render but if in the final render I got the laptop was very slow and it was almost impossible to work. in the end I had to render on the computer of a friend of mine who helped me because I was not going to have time with my laptop. but the problems did not end there. I was finally able to finish, I know that my work is far from being perfect, I started in March of this year to study 3D and with Blender but I know that I gave my best in this challenge, my first, and that even with obstacles I could finish . I felt like this was the true story behind this image. Success for everyone!!!
