Almost all of the letters looked like they had been cut off right at their baseline and x-height. Is that your intention? That could also be due to low resolution. Care to give us a PDF of higher resolution?
Also, the s look rather imbalanced and the stroke on the upper part of f need to be thinned -- like Rotis' c, it is in danger of falling over, albeit much less so. But I dig the g :)
Any possibility of using the face at text size? It looked robust enough to me.
