This neat, but 1 suggestion though
It looks like the brick is only moved 1/4 of the way over, maybe you should make one that is 1/2 the distance? so it would be in-between the studs.
Such as these bricks do if the 1x2 brick is placed perpendicular to the plate. Notice how the stud is in-between where there would normally be 2 studs, offsetting the brick that is placed on it by 1/2.
Nice job, though. Inspires a lot more brick makers :)
