I've found that www.reddit.com/r/calligraphy is a really great resource (of course it'd be great to see the same community develop on Steemit)
As for you work -- keep at it! The human hand is subject to so many quirks of muscle memory, comfort, and control that it is no wonder that consistency is difficult to achieve
Thanks for the resource @bypic, I'll make sure to check it out. I think it would be awesome to build a community of letterers and calligraphers on Steemit. And I agree with you, practice makes progress, so I will keep practicing and hopefully look back at this work with fondness. I do feel more comfortable with lettering than calligraphy. I just can't make the nibs do what I want. That takes years of experience. The best calligraphers I've watched are incredibly accurate. My hands and muscles don't move that way ;)
Nibs are creatures with their own minds, indeed! We'll all come to proficiency I know it
