A coherent derived work. (I did not check the validity as basic Ascii, but it looks complete, except for the following.) Alas, there is no lowercase! A pity since this is quite feasible (relatively easily) at this fair size. I am not begging you, just telling you this is not a font (else you could remove more subsets without problem). As is and all the same, we can enjoy the well-distinguishable glyphs you could import from a plethora of sources that show this grid size nowadays… Because, as a specialist, I'd state your derived slightly on Windows' raster “4x6” font (seen in the current Windows OS and before, as I already mentioned in the French pixel art article at Wikipedia)… So, if I cannot encourage forgetting the sources (ripping without crediting), the balance is good (light type color and fair readability).

More comment of mine when you add the lowercase (not cloned from Microsoft again, please), i.e. with more effort.

Bye!
