At this point I decided to develop the composition on an incline plain to give to the scene a greater sense of dynamic and drama.
Then using a soft round brushes I added haze and smoke in order to push the city into the background, creating the impression of a place under attack (Fig.05).
Then, with a quick sketch using the Hard Round brush; I started to introduce the figure of the mech. I decided on purpose to leave some parts of it out of the composition to emphasize his proportions. In this phase I tried to define the volumes and shapes of the mech and I decided to arm it with a laser beam exactly as a spider shoots is thread. This laser will be his weapon of destruction (Fig.06).
In Fig.07-08 I added more details on the mech and continued using only brushes to give it a painterly feel.
Then I started to focus a little more on the laser beam and especially on how the hard surfaces of the mech are reflecting lights. I also added some LED lights to the armor. I gave a sense of incandescence later on when the composition was almost complete (Fig.09).
At this stage I start to feel the need to make the mech interact with another object, so in the lower right corner I decided to put a complementary subject in the scene; a sort of military truck who is escaping from the mech monster.
I sketched the silhouette like his trailer was experiencing torsion of a high speed and the violent swerve, just to make it more dynamic (Fig.10).
