@malhomsi Eevee has a lot of potential, It’s possible to get close to cycles but in real time, it’s crazy when it works. But it’s still really buggy, be sure to have a 2.79 backup of your model!
I took all the lights and added a new key light, due to the material I use the shadows lose some sharpness, take a look (with a placeholder material):

It already looks more “actionish”! What do you think?
Thanks for your help!
