I'm curious, which Dota 2 UI skin did you use as a base? I don't remember Dota 2 ever having such an UI (or more accurately, the HUD Skin).
I think it would be more appropriate to design a UI for the Living/Undead Nerubians (one of them uses a recolor of the other, it is probably the Living Nerubians), Ice Trolls (the UI has the Lordaeron Crest, which doesn't fit imo), and Wildhammer Clan (a faction with incompatible UI imo) rather than the other human kingdoms. It would also be much better to add faction crests to all the UI's have you been used (it can be applied to Ice Trolls UI to remove the Lordaeron Crest).
I'm remember the days I spent designing UIs for your pre-overhaul factions (most of which were vanilla faction UI recolors). Beyond the UI, I even worked on the cursors. I'm also in favor of changing the cursors for your factions. I have cursors I've created or used for the factions (Dalaran, Fel Orc, Lost Ones, High Elves, Draenei, Scarlet Crusaders, Forsaken, etc.) that I can share with you.
I also noticed that Tile05 and Tile06 are missing. I'm curious, but are you going to create and release those parts as well?
The last things I can say that, the Kul'Tiran UI looks wonderful. I really liked the Draenei and Nightborne UIs back in day, even though you consider them mediocre but this Kul'Tiran UI should be High Quality or even Director's Cut.
