Amazing concepts
Some nice concept ideas here I feel like you could have a small border on this piece to accent the concept designs more maybe a border with the same yellowish colortone, Though I am uncertain of this invention being real the way in which it is drawn truly "MATCHES-THAT-OF-SOMETHING" that could be seen in real life, In particular the separate drawings of instructions regarding the functioning/abilities of this device make for a realistic depiction of a "BLUEPRINT-OF-CREATIONS", The white background is a nice "SIMPLICITY" for the complexity of these drawings and their bright warm colors, The addition of the person in the corner is an interesting contrast in that he’s drawn more carelessly regarding detail Still his addition feels essential to the piece as a whole.
