This is still a work in progress. I happily accept any praise, criticism, full-blown rants, monetary gifts or suggestions.
Background/Basic Info
Aesthetically, I wanted it to look very curvy and flowy. Naturally Tengwar was one of the inspirations, but I don't think s'Illaent looks too much like Tengwar at all.
I started by arranging my phonemes into a neat table. If you look below, you'll notice that quite a few of the phonemes are in incorrect or odd positions, but that's just to make them all fit evenly, so please don't bag on me for that.
History
Erm... Not much history for it yet. All I know is that a person invented this script a century or so before my story will take place, so yeah... I'll fill this out later.
Oh, and also, it's named "Luraesaka s'Illaent", or "Modern Script." Often shortened to "s'Illaent", or "Modern."
Letters
Underneath each character I give the standard romanization, followed by its XSAMPA equivalent.
A dotted consonant marks palatalization, while dotted vowels are doubled/lengthened.
I also have no punctuation yet, but I'm working on that.
Explaining the Featural-ness of it
Basic Structure
As you can see, all characters have some sort of basic circle or semi-circle, and nearly all have some sort of stem. I have yet to come up with in-universe names for them, so for ease of use I'll call the former the core and the latter the stem.
How each letter relates to another
Note that the front column will differ slightly from the other two, usually involving some sort of merging of the middle and back characters for that particular method of articulation.
The stopscan be considered the basic characters for their column. The rest of the characters derive from the stop character in the same location of articulation. (Haha, rhymes. >_>)
Stops can be made into nasals by simply adding a horizontal stroke or bar at the end of the stem.
The approximants replace the long, curved stem of the stop with a short, straight line and move it to the opposite side. The core remains the same.
The fricatives are simply derived by doubling the core stroke.
The open vowels replace the semi-circular core with a full circle. Usually a writer will merge the stem and core of these characters into one, smooth stroke.
Open vowels are made closed vowels by adding a bar, in a similar manner stops are made nasals.
Samples
Here's a sample for version 2: the first line from the Tower of Babel passage. I really like it now, I think it looks much better than v1. Of course, comments/criticism are still greatly appreciated.
Transliteration:

"In the beginning, man had one language and shared one speech."
or
"In the beginning, the world had one language and a common speech."
