Here is Darth Maul on his speeder with his cape.

Darth Maul: I glued the joints together and lengthened the legs a bit to get a deeper position in the seat. I sculpted the cape and the hood, as well as the bracelet that controls the probes.I used pieces of the "skirt" to make the sleeves flying in the wind.

The speeder: I just exchanged the oversized foot with a transparent rod. I placed the probe on another thinner rod. And finally, I covered the base with sand.

We finally get the character as he appears (furtively) in the film.

See ya !
