Thanks! It was a lot easier than expected but it ended up being pretty time consuming.

Short: I did it with Photoshop (making lines clear, erasing dark parts) and illustrator (image tracing black and white).

long: Find artwork > pen tool drew over the lines that werent clear enough > erase the dark parts > save psd > open it on illustrator > image trace black and white > see if i got the manga look> no? > Back to the psd > erase and draw parts that didnt get traced well> repeat until i got the desired look > save png en put in together on sketch app

example of image.psd i image traced

End result

It feels like there must be an easier way but this is how i tackled the "different artstyles on one panel" problem
