This is what my original doodle looked like (also on instagram)

After scanning in grayscale @ 600dpi

And after isolating linework in Photoshop, it looks like this

How does this look? I've always done pen/marker doodles and digitizing is new for me. I'm also very bad at cleaning up a scanned image :(

All feedbacks, suggestions, advices and tips are welcomed and appreciated.

Thanks! ♥
