I really like this shot here

In this picture it looks as if the Sovereign is half way through his level (needs 20 more exp but seems to be halfway filled currently so my guess 40 exp for level 1 to level 2?). In the top left there is the number 15 under his portrait. This number seems to match the spell power icon next to the attack and defense icons in the bottom row. So I will guess this indicates mana?
Underneath the bottom center portrait there is an icon with a varied color theme, I will guess this at the number of troops / heroes in the players army. In the card photo where the spell research was shown that number was at 167.
Now the difference in the upper left portrait and the bottom center portrait seems to be that upper left is always your sovereign, whereas the bottom center is your target.
In the picture here 
the bottom center icon is showing the progress of the city. Also the bar to the left shows information relevant to the bottom center target (in this case city info). In this case I am going to guess the sovereign is level 1 with 10 spellpower / mana and is halfway through his level. He has 113 creatures / heroes in an army somewhere unless that population (which is 112) counts instead. In that case it would make sense to say Sovereign + 112 population = 113 seen below the city icon bottom center. Some interesting questions I have are that there are no open plots to build on in this scene. So will a tech be required to expand further as this seems to be the first city and likely in the long run to be the most strong in the due course of time.

In this image above I find it interesting that the sovereign seems to be level 3. His attack is 9.5 and defense is 7 instead of 9 and 3. Spell power and hit points remain constant. The next question is that are the items comveying the extra stats or the levels? The bonuses increases seem paltry for both together.

The lighting is fantastic in this screen above, and a very nice POV shot. I will also surmise here that this guy is likely fallen whereas in the picture above we see Man.
