Monster design sketch dump

Hey guys~ See I told ya I wouldn't be using this account much XD. But here's some things that I found decent enough to upload here, even though they're not work related in the least. I figured it was theme appropriate anyway~
Hmmm so I suppose I should talk about these~ I'm really not sure what to say, I started drawing them on a whim and then I started trying to focus on making something ACTUALLY scary...but I realized that I have no idea what features people are actually frightened or unsettled by.
Things I find legit frightening and are my favorites are things that you can't really see, or you can't figure out. Like things underwater that you can only catch glimpses of. That's my favorite, but idk if others are really into as well. Also I'm not sure how to properly draw that kinda thing.

Anyway, let's seeeee, I didn't really have any real idea behind most of these...I just started scribbling and things appeared....Some are done in Photoshop and others are just MSpaint.

Oh! And if you're wondering why a few monsters are missing from this then I'll tell you that I'll be posting a separate sketch dump on my main account with all the monsters that I either didn't like or were too derpy to really take seriously.
If you have any questions about any of them feel free to ask me.
Download for full view and enjoy~! If I answer comments they will be from my main account.
