Its much like just vectoring an MLP character, use the pen tool to make shapes over a screencap/just winging it. I use photoshop for vectoring, even though most use Illustrator. But I have next to no experience in illustrator
It works well for me, but like a said, most professionals use Illustrator. But if you're not int he money range of adobe products or dont want to torrect, Gimp also does vectors well! Vectoring isnt too hard. I make MANY minimalistic wallpapers so I guess those are some examples.
Yeah - I'm kind of in a similar boat, I could always try out illustrator but I couldn't be bothered trying to learn something else. However, that said, my friend has illustrator and knows how to do these, I want to learn myself and I didn't know these things were even really possible to do in Photoshop. Is there any more accurate ways of doing this without using the pen tool?
