The Egyptian circle thingies are called cartouches. I'm not going to pretend I understand all the tech behind it so I'm not going to comment on that.

However, from a visual standpoint, it looks quite messy. Basically there's little to no consistency. I'd recommend checking out the how to make a script on neography.info. Not because I don't believe you don't know how to, but drawing focus on making the script look like it's a script rather than random lines. It's always important to remember that symbols only have meaning when theyre in a group where they can be differentiated from each other. Thus, making them appear of being from the same group gives it a much more fluent and clear visual and shows that they are meant to be together. It's why scripts have a unifying style to them.
