Scott, thanks a lot for your advice!
Tried it with some awesome results, rendering one of my frames under Eevee, took about 10 seconds, compared to 15 minutes under Cycles.
Now, I understand that Cycles gives a lot more of power and textures and stuff to the rendering, but with my PC I can export some basic animations using Eevee and keep learning this way. I will try to work my way to learn more about Engines so I can obtain better performance and better results.
For instance, I noticed that the fire effect that runs very smooth under Cycles, does not perform well at all under Eevee.


But I guess its the price to pay for faster render.
Anyway, thanks a lot for your comment and your advice, I will definately invest some time on learning more about this.
Best regards! Hope to connect more with you in this journey.
