I got this idea from Alex Negrea, he is currently my favourite digital artist, his skills are incredible and he is very dedicated to his art, I definitely recommend checking out his work! :)
So these drawings are a little bit.. rough, because the idea is not to spend too much time making it neat and rendering it well, it's to build your visual library, anyway I have done a few pages of these which I will post below. I also recorded a video for one page of them just so you can see the process, thanks for watching :)
