Those Gallic units... are they one unit with different colors and things like that within it? Or is it a bunch of different units standing in the same place making it seem that way?
The Gallic units are individual units standing together and charging. Prometheus wanted to show off the Gallic work he had done. He made those in a week, I believe. If you notice, most of them share the same model. There are other Gallic units made, some of which you have seen, and a few yet to be made. Our unit lists are basically limited by model. We have a small number of unique models a faction can use, and then they must be shared. We can have many more unique units (500) than unique models (255), which is especially tough because the unique model limit includes commanders, animals, siege engines, standard bearers, and so on.

as for the Briton Rycalawre. you said it was work in progress, they look lovely but i would say the colors of the garments they are wearing need a slight change, specifically the sleeves of the briton unts
The Rycalawre are a unit of elite warriors. They used bright colors to signify their status, among other things. These are not the final colors, but they will be more colorful than your average warrior. What, specifically, is the issue with them?

Please tell me that these pikemen are from a screenshot from the game and that they will hold their sarissas with both hads pleaseee!!!!!!!!!!!!
They will be. We still need to do the animation for this, and the overhand spears. That is coming soon, however.

In this picture look to your left and up a little. You can see the gold board which the flag bearer is holding. Maybe you should darken it a bit because it sticks out so well. If someone had blurry vission he's think it was a banna.
Well, this may be a matter that we will look at, but according to our Celtic scholar, the Gauls (and the Celts in general) "polished the hell out of their metals."

Mind if ask what is the type of unit next to the Argyraspids in the unit cards?
Not at all. However, you will have to be more specific, since this is a group of Ptolemaic units, and as such no Argyraspidai are shown.

By the way, the icon was indeed Parthia - as I have noted, I forgot to change the filename before uploading it. Silly me.
