Due to the popularity of my big, overgrown gecko, and MANY questions as to what it looks like, how big it is, how it moves, I've come up with an idea: You tell me.
SCP-682 is a big, nasty critter with the ability to adapt to almost anything, so there's no real "wrong" way to draw it. Six arms? sure! Wings? why not! A twelve foot tongue covered in blades and suction cups? …ok, that's pretty odd, but have at it!
It's like a really odd inkblot test. The only thing i'd ask is you keep the basic skull shape that's shown in the picture, but it's really up to you. Myself, i always saw 682 as a horrible cross between a armored bug, a deep sea fish, and a iguana, but that's me.
I'll try my hand at it as well, but be warned, my artistic skill is at the same level as that of a wombat. I'll be interested to see how 682 looks filtered through more capable hands…
