More Inventors

In my strange inventions booklet for my personal project I need six inventors for my six inventions. I've already completed the first three and now I've just finished the last set of three. They all took a lot of time to make but I finally got them all looking how I imagined they would. I tried to vary the colours for each image and change the pose of them as well as where they will be coming from when i put them in the booklet. (This is why one is upside down.)
