Oh thats really great tutorial thanks! I think it will help and I might use that for my Vriska arm too.
I was talking with my friend about doing an orginal Homestuck cosplay and she suggested something along the lines of steampunk. I sketched up some designs for my Vriska(mainly god tier with aspects of her FLARP outfit) and her Aradia(mainly robo with aspects of her god tier) and they are looking really awsome right now. If we are ever serious about cosplay this then I think I will try and drag my other friend(Eridan) into our little group aswell.
I might post the designs later once I clean them up and color them.
