This is pretty good! This looks like what a lot of games have as their UI’s the block’s for each items.
I already see great potential for this either by selling this pack on it’s own or making a game our of this.
Just saying you may want to but a stronger watermark on the UI’s in the top right corner (The “Shop”, “Trade” and “Inventory” buttons) in case they get stolen.
I am assuming the one in the bottom right is for a case or a loot box.
Over all pretty good I would give it a 9/10 losing one point for being very similar to other UI’s in other games. If you could figure out a way to spice it up it would be great but this is already a great UI pack on it’s own!
