How Should I Shade My Exclusives? (Patreon)

As most of you know, I have two major shading styles, one that's more cell-shaded and cartoony, and one that's more smooth and "realistic." As I've gone through all these exclusives, I've been wondering, should I try to mostly use my smoother shading, focus on the cartoon shading, or, what I've kinda been doing, go with whichever is closer to the source material? (ex. Broadway was cartoon shaded since he was from a cartoon: https://www.patreon.com/posts/exclusive-broad-71172478 and Splinter was smooth shaded since he was from a 3D rendered show: https://www.patreon.com/posts/exclusive-69079610) 

If you have any other suggestions, feel free to comment them!

I'll also add that no matter what, I'll try to get some of both styles every now and then, but primarily stick to what will be decided in this poll
