In most cases, people usually know what they're getting into when they read a story. If you're reading a horror story for example, you'll expect to see some scary or gory things. BL/GL- likely a lot of sex scenes. Etc, etc.
For those pages you posted, I'd add a "Content Warning: Gore" message at the very beginning of the episode(s). And if you go further, such as say a detailed corpse, or something that could be potentially triggering even to horror-lovers (rape, death of a child, to make some extreme examples), definitely mark the episode as mature and make very specific warnings at the beginning of the episodes.
Otherwise though, I really wouldn't think too much about it. I believe staff or a reader will let you know if they feel your comic needs a little censoring/mature labels!
