Ive tested your plugin, and its quite nice. I like how so much is customizable, and yet it all remains easy for users of all skill levels to handle. I appreciate that. Despite what I wrote below, I still think its a good plugin that stands out nicely. It just has a few rough edges. I'll give you 4 stars. Mes observations:
1. The portrait being separate in the picture folder works fine and is a neat idea (in case someone wanted a bigger (or smaller) portrait shown. Ex: Cheerful portrait alt-version just for the victory screen. But if at a smaller resolution, then fullscreen'd... This causes an unintentional blur, which is ignored by sharpening plugins for some reasons. Could it be that your plugin applies a % scaling of sort?
2. There's a very noticeable slowdown/lag when any part of the victory UI slides into place.
At the time of writing this, Im at a siblings' place, keeping watch/caring on his cats while he's away for the week (until the 15th?) It might be a performance issue given Im using his laptop at the moment. I may test it again once I'm back at my place and see if any performance slowdowns still lingers, when using my actual COMP. Maybe its a limitation of the engine itself?
3. If using an unusual screen size set in the project's settings (example 816 width) some of the UI will be bleeding outside of the player's screen (the currency counter at the bottom right is the first victim). In my case, my 4th character has no place to be displayed.
4. The LEVEL UP stats difference AND the skill/ability learned screen looks great, like a lot of the rest seen on the previous screen. Very clean and pleasant to the eyes. Sadly due to my BitmapFont plugin, the words are too large, size-locked and thus overlaps in many parts... BUT others not using BitmapFont plugins will be able to adjust and circumvent this issue specific to my end. This isnt your fault, its on my end.
