Surprisingly legible for a pixel font; nice clean look

Well, I wouldn't say it looks so legible.
There is a lot of odd stuff, for instance:

-t is too high, and its crossbar too;
-it's too tight for this size. try 2 pixels spacing, "stem-to-stem";
-vwyz are wide (or are the other letters too narrow?);
-VW are really wide;
-bdpq looks strange: the bowls should be similar to o;
-x is narrow;
-A's counter is too closed;
-the numbers seems to differ in style from other characters...

I think you still have a lot of work to do here.
Good luck.

Made some changes (thanx Eduardo) and think that is better now. Maybe need to make 'h' 1 pixel narrow.

Here is the new version with some kerning work too. Thanks.

Well maybe the face looks more regular now, but too standarized. The first example was more inviting for the reader, and i think that the "strange" shapes helped on ditinguishing the word shapes, wich is not so easy in pixel grid.
