I really like the textures you are using as the background. Since its kinda shadowy , can you try adding shadows to the edges where the new panels meet? as if a light is shining down on them. And possibly add a border to the edges so they look finished off.
Keep your buttons centered on the left and right panels next to the map and make the other areas chat areas.
If we can see a picture where you are alive that would be nice
, party as well if you got that set up.
Nice start overall
