Here's my step-by-step presentation of art " Fighting game ". 

Step 1 : sketches, search of good-looking angle. I was enspired of eastern martial art poses in famous "Matrix" movie and monks picture in cyper-punk style. 

Step 2 : Cyperpunk-monk character

Step 3 : She-killer character

Step 4 : seeking a right angle for Her flying pose. 

Inspired by Trinity( Matrix)

Step 5 : models in room with perspective. Again sketches in choosen foreshortening.

Step 6 : walls fitting with color. I tryed to make more action and eventually chose the most exstreme angle in my opinion.

Step 7 : walls creation. In order to make volume effect I made outer and inner parts and put them in perspective. 

Step 8 : heroes in scene. Line, colorizing and embient occlusion

Step 9 : finally heroes are in their fighting room

Step 10 : shadows and outdoor light definitly has changed previous picture brightness. Location becomes more dark and I start to fill more dangerous situation in it... It looks like He will loose this game...
