it's not bad for a second map. however like MattAttack said you should switch the factions so you are GDI and enemy is NOD since GDI use NOD structures, also maybe make the path that leads to the Obelisk less 'interesting' cause i pretty much walked there after killing 5 minigunners hoping i find something there(maybe switch the flame infanitry and the 5 minigunner squad) and populate the map a bit.
