hey...my surname is martins :O
about your typeface, I really don't like the skewed C's, the 0 and I don't think that the G works. other than that I like it very much.

I think that a heavier weight should be another consideration. For instance is you designed this face in 72 point art what happens to the characters at 24 point?

I think your dots can stand to be heavier overall (. : ; i j)
A problem inherent in monoline fonts is that these dots look much too light when they are circles of the same width as the general stroke weight. They need to be enlarged slightly and/or made not quite so circular.

The foot of the majiscule R could be pulled out a little into the bowl (away from the stem), which would allow it to be less limp looking.

(Is Dagenham Dave from a Morrissey song?)

Oh, also a larger bowl for #9 might look good.

You have family problems here. Some of your letters are nice and geometric, while others are not.

Letters I'd drastically change would be: C, c, K, @, and €.

Letters I'd moderately change would be: G (too closed on the top or too open on the bottom), M/W (adjust one to another. I don't mean mirror them but adjust them to match), S, s (they are too big and too wide on the top half), Y (it's heavily falling right), 3 (too big top - adjust it to 8), 5 (ending should be more left or move the top left stem more to the right), 7 (unstable just as Y), 9 (too narrow).

Nice start.
