Miniature models come in two flavors for me, DnD or 40K (which is really just my way of saying fantasy or sci Fi aesthetics). So, when I saw this, my first thought was that it was an imitation Tyranid model which has taken inspiration from one of the critters in the Star Wars movies. Imagine my surprise when I check and see that it's got nothing to do with Tyranid at all and is just the Star Wars monster.
Great sculpt, hope to see the final product painted up! Thank you for sharing.
