Looks good, and it seems everyone is satisfied with the evolution. I, too, agree that expansion icons are not necessary. For myself. I usually mount on matt board for durability, since "standees" are meant to go in a stand.
- Standees will see more wear and tear than for a card in a deck. Yes, if homemade, one can replace a worn one, but why bother. A card (sleeved or not) is going to see more wear and tear in this type of use. In the old version of Talisman using such, these were the first components to be redone. And we were plastic veneering everything in those days for durability.
- I have also found that stands (which I use in all games in place of figurines) tend to bite into the standee (if they are any good) in holding onto the standee for a solid playing piece that can moved.
- I would go without the frame and have a place for text. Sometimes the character image isn't enough in a large game or set against a colorful board for quick location and identification of all standees in play... especially for those with a background. Then again, maybe it's just my tired old eyes. It's another reason me and mine don't use the "little gray horde" since we don't have time or talent to paint them. And if the standee is to be decorated, then decorate it with something useful perhaps.
The shape could be made card size so that it could be mounted or sleeved; the ones we use are narrower so they don't fill the view of the board as much. Without the frame, any background can be full bleed; a stock background could also be offered like one on character cards for those who have the savvy to paste in a well masked figure.
Here's an example of the type of standee we use. We tried a frame at first that was designed to match the character card template itself. It was great to look at but too much in play according to three test groups I use before releasing something. Click the image to see an enlargement in a new window.
ADDENDUM: In a SE plugin, the bottom frame for a label could be PNG overlay. To individual preference, the label layer could be turned on or off as desired. Also various "flooring" could be another layer that the player could choose when pasting in a PNG or masked figure to let a stock background show in combination. Any element seen here is available for use if so desired.
Oh, and for mounting, we've found that standard cereal box material is a great compromise between the thickness of matt board and just a card stock weight. With the right size of sleeve, you can even sleeve them, since the so-called "Euro Mini" sleeves come in two slightly different sizes.
