dreamy skiff
Hey! I think this looks good - reminiscent of the Slayer icon for Runescape (which is a pretty iconic design).
If I were to be nitpicky, I would say that the dagger in this case is too big compared to the skull, but if you're planning on swapping it with a WWI bayonet then maybe that can be resolved at that time.
I think another element would be positioning the skull in a way that makes it seem like it's on the ground, so that the visual stillness of it can help reinforce the finality of the act depicted. As it stands, with the drips on the bottom, it feels a little too dynamic to also look time-worn and old via the lack of upper teeth etc.
Either way, it looks cool and I like the concept!
