I agree with those who said this has a nice flavor. Do make sure polishing it up doesn't end up neutering that.
About the vertical proportions: I like how the ascenders are long. However the "g", "j" and "y" are going to very different depths; I would use that of the "g" for all of them. Now, if you're actually going for variable lengths for the extenders, that's a pretty brave move, but should probably apply to all of them (I mean even the straight ones).
BTW your overshoot amounts are inconsistent (and missing in the "f" and "g"). The overshoot might also be a bit too modest, which makes this design more suitable for larger sizes; for smaller sizes more overshoot would help.
Lastly, I would make the tittles more prominent (especially considering your tall ascenders) and that huge beak on the "r" will give you a lot of spacing trouble...
