I realize I suck at this. Perhaps someone can give me some suggestions for improvements? The letters are J and D.
The last one is the only one that, to my eyes, doesn't comprise a S.
But, unfortunately, J still has lot of T about it.
With a tricky letter such J, I think you should clearly show the descender, instead of trying to incorporate it.
Have you tried to modify your 6.46am one transforming the leftmost curl in the J's descender?
I don't think you suck at this, your forms look good to me. I did this sketch to show how you might want to heavy up your shades (thick parts of the letters). Heavier shades will define the letters more and differentiate from swashes.
I know you're trying to combine the two letters so it's all one continual stroke, but that may be what is preventing the J from really standing out. If you want the design to be all one stroke, make sure that the transition from one character to the next is thin... any thickness will be confusing.
Also, I've made the J stem and the D share the same double stroke... why not let them really echo each other? Like they're dancing... let them hold each other close. Just my two cents for what it's worth. I know you'll end up with a great design.

I agree with TypeSEtit, you need to add weight to your where your stems would be. Also, I would consider experimenting with a cursive "J", one with an upper and lower loop. I think you could make some nice vertical rhythm. Even for the fanciest of uses, such as wedding invites, I think there is room for completely straight portions, it adds a degree of variety that just makes the whole thing look more elegant when balanced nicely. Imho a fully curved monogram tends to be too flourishy, too decorative.
Please excuse the rough comps, just trying to provide my train of though.

I have a similar problem creating my IP monogram.

I end up looking like a J, and P end up looking like a D
Funny :)
