Inventor's Clothing Influence Map
I would have to say, I adore the goggles with the hypnotic look to them as it gives off a crazy look. I would change the colour of the goggles to green, dunno why but it shows more of the craziness than the red does.
The clothing for the inventor needs to be a lab coat, white shirt and bowtie. It gives it a inventor look. The bowtie might need to have a red pattern to it. Having it black is too much of a boring colour.
As what Dmitrij suggested, giving my inventor robotic octopus like arms seem to be a good way of showing that he needs more hands to create his inventions.
The hair has to be messy, to show that the inventor had some accidents when trying to get his inventions to work. Having a beard would look weird so I'm not going to add that.
