Matt - you've greatly improved in your consistency, especially in the slant of your letters! It does help to post photos that are taken straight and head-on (basically, what you'd see if you scanned it); anything else can really alter the viewer's perception of the letter forms, and we may not be able to give you the best advice based on that.
I second Jean's recommendation to try another ink. I know there are some people that love it, but I find that I don't get good, clean lines from it. I'm a Moon Palace Sumi fan myself.
One thing that does stand out here is the right line on your ascenders is a little heavy. It should start and finish with a hairline. I'm on Team Upstroke for that line myself (I prefer a full hairline there, so I use an upstroke vs. downstroke), so don't have any great tips to give you on where the weight should be on it or how to achieve it, but studying your exemplars should give you a good lead there.
