I have a thing about designing such critters – I don’t really know why, I just do. So here they are.
First up is a reoccurring character of mine who straddles both elves and demons – my part elf, part succubus, Fade.
Next up is a succubus design
And now for an Incubus (for the time being, ignore the writing – I did this for a charity calendar, and my original without the lettering is trapped on my old PC. When I recover it, I shall be uploading the original piece!)
Another succubus, this time in coloured pencil
And finally, another part human, part demon, for a piece of pin-up work
