·you haven't updated the gif to make the "g" rotate

·you could make "E" a rotated "3"

·you could lower the lowercase "s" and "z"

·you could make the "F""f" rotationally symmetric, so that you coul lower "f" after

·you could make "L" a rotated "7", alternatively, you could make the "7" a rotated "t"

·you could make "N" the [sample], so that if you rotate it, it becomes "v"

·you could make the "O" 2 bricks higher, and use a lowered version of that in "0"

·you could lower "8" 2 bricks, and move the og 8 on "B"

·put a dot below "I" so that "I" is a rotated version of "i"

now that i think of it, you could add a tail to "l" and make the "1" a rotated & lowered version

aswell as removing the tail on "t" and makin the "+" sign a lowered version of "t"
