An attempt at mimicking an anime screenshot-styled pic, based off a sketch done by Patteellama: http://patteellama.tumblr.com
Some stuff I noticed when observing various screenshots is that the lines are rarely pitch-black, but more of a darker grayish color (especially noticable when characters have black color on them or are standing against black backgrounds/objects), so I went with that, and quite frankly, I'm satisfied with the result.
As for the subject of this pic? I'm not too fond of the shipping thing, but Blaze/Sonic is my only exception...they work so well together, unlike the whole Sonic/Amy and Blaze/Silver pairing (the former being more one-sided and the latter being more of a sibling relationship).

i think you got your goal, tbh i thought it was a screenshot until I read your description. my first thought when I saw this was "really? they're uploading a screenshot from a cartoon?.. is that a thing?"
