Less spoilery content warnings for Collision comic (http://iperyys.net/kuvatus/dinoscollision.html or https://www.deviantart.com/kosmonauttihai/art/Collision-page-1-859253083):

- visible blood, as previously mentioned
- no wounds shown in graphic detail, though
- mostly obscured view of dead animals
- somewhat downer ending

I'm not sure that's all that much more reassuring, but that's not the point of content warnings, is it. It's to help you prepare for what you're about to read, or to decide not to read it (and no judging if that's what you decide).
