Not a bad start on breadboard. You may want to fix up schematic some to be a box with appropriate pin labels (listing each pins I/O function) and actual pins and terminals as it doesn't appear to have any. It would be good to move the connectors in pcb to their correct positions and again add appropriate pins so the connectors can be routed in case someone wanted to put it on a board and probably modify silkscreen to trace the outer edges of the board.
