The main difference that I see is the proportion of the sample. The sample is very eye catching with it's tall, narrow proportion. But, as you say, you were not looking at it when you did your own lettering, so it is understandable that your proportions came out shorter and wider. Your spacing is very similar. The one letter that jumped out at me that I did not want to mention until I knew if it was included in your sample was the m. I don't spend any time looking at all the variations of fraktur - so maybe that shorter stroke appears all the time - but I found it distracting. If you like it, by all means - keep it. If you are going to try another version that is closer to your sample, IMHO, you might try the m with three matching strokes and see how you like it. The sample is really beautiful and I can see why you would be interested in having a full exemplar. Thank you for sharing.
