Excellent details. A really nice feel to it. 10/10.
As far as UC is concerned. I looked at every other black letter, and based my upper cases around a select few, a bit like you would've done with the lowercase. You have to do about 2-4 different styles of black letter uppercase's before you can really start to develop you own style.

Great font! But I'm waiting for some better and great glyphs... I think you can still working on it, please.

I beg your pardon: my english is disastrous... I hope you make some other glyphs on this font because I like it!

Don't worry, everything comes in time if you do not give up. Some need more time. For almost one year i only published sets strictly UC or LC, not even numbers nor punctuation. Some of them became basis which led to a TESTAMENT version i publish today after so many tryouts and transitory phases, and sometimes what i felt desperately dead ends at some point... Obviously you try to develop a signature, even in traditional styles, it takes more time than just copy things already existing elsewhere.

@Demonics. I think it's always best to start simple. I think your idea of basic angular forms is the best place to begin. You can always 'trad' it up once you have the basic forms, if you feel it needs it. That's exactly the same way I do my blackletters.

Interesting :) I, unfortunately, know nothing of "blacklettering", so can't come up with real suggestions. If in the end nothing comes, I suggest putting p,y on the baseline, it becomes uppercase P, Y. Put a stroke on P, it become R. Develop B by putting a circle on top of b. You can make the K from that h of yours and so on :) Solutions are very unnatural for blackletter, but if nothing comes, you can't hurt anybody by doing it, I think. :)
10/10!

Another gorgeous one. You're on a ROLL! Caps, please!

Tips for UC in whatever form they take... In keeping with the large x-height, and the condensed proportions, I suggest keeping the US as short as possible (possibly even slightly shorter than the ascenders) so they feel proportionate to the LC. When using a small grid in FS, it's common for the UC to feel more condensed than the LC, especially when they're taller… a trade off when trying to keep the vertical strokes and counter spaces "even". OR… go crazy decorative with the UC… these beautiful LC forms could be just the tip of the iceberg and could be the perfect stabilizing force in contrast to something more flamboyant.

Oh, never mind the UC, your LC is just great. Love the z.

For blackletter inspiration I always turn to Dieter Steffmann. You should find something in his extensive archive as well.

A beautifully coherent and balanced design. I'm sure you will make an equally good job of the Uppercase. 10/10

Great work! Don't have much to add to what others said about the UC.

10/10 who needs caps when the LC is so finely executed?

Excellent use of the angles.

usually i'm not into black letter but this one is really sexy. my ten to you. don't give up on the UC this is gonna be great!

You are really on to something here, the little kinks in some of the glyphs work extremely well. Looking forward to the rest of it!

Awesome blackletter! This is one of the best I've seen. 10/10

Cool blacklettering! Looking forward for the UC.

The UC looks great so far! And numbers too! =D

Keep going!

Uppercase is looking mighty fine. You're defo doing it the right way. Simple forms then adding the traditional elements. They'll be a few that will be a pain though. I always hit a couple of roadblocks, but that's the challenge.

Loving the style of the UC… the dual stroke is a brilliant way to solve that UC/LC proportion challenge. This looks traditional and modern at the same time.

This is getting better by the day!

I must agree with what everybody said so far. UC looks incredibly promising.

Magnifique!

What's good about the UC is that letters share many parts. So sometimes by making 1 glyph you make 5 others.
