Time to wrap up. We have three entries as follows:
From Icecold, what I would best describe as a lurking horror. Exactly the sort of creature that would scare the bejabbers out of your standard dwarf. I particularly like the runic-looking etchings in the rock--sort of mine signs indicating that there is a danger ahead.
Good thing I have a bit of experience in drawing skinless things.
Next is GreatWyrmGold, who encountered the same sizing problem I did when I first submitted to this thread. Actually, I found sizing the image in Paint works well, although you still have to work on making it legible (took me several tries). I like the small cloud of bolts. When Quelge finally fell, it was after a sustained period of bleeding out in a lake, which this seems to capture nicely.
Let's give a round of applause for my digital camera, which has left this image a bit bigger than the piece of paper I drew it on!
Okay, it's not colored, but I included six crudely-drawn dwarves and a bunch of cavern wildlife! And the shell is actually enormous! And the head looks like a skull with some muscle and sinew on it!
Last one is Chewie, whose unfinished work is still impressive--a sort of Slenderman version of Quelge. I note that what looks like the right front leg seems to articulate backwards. I don't know whether or not this was deliberate or a mistake, but it adds to the unsettling look of the creature, and I like it.
This basically just became a greyscale painting of a toad without all the specific features the FB has. But I was quite surprised by my painting skills and since there's not much going on here, I thought I'd upload it anyway.
I also stopped painting mid-work while I got on the background. So it's not even finished.
Thanks, everyone for contributing. I'm giving this to Icecold. Congratulations!
