Ponies in Rhul

I made this MLP:FIM/Warmachine crossover for a competition one con in my city. I didn`t win anything. However, I`m glad that the Bronies I met there like my picture.

Drawing this picture took two weeks, I`m just a beginner in digital drawing. I`m rather satisfied how I managed to draw the mane 6, but I noticed something is wrong with Fluttershy. One friend told me, that it is the shape of fluttershy`s head. I think that also the shading of FS should be more prominenent.

And somethig about what is happening there:
(Pinkie fired a cannon and unwillingly made the mine entrance to collapse)
RAINBOW DASH: Pinkie Pie, are you crazy?!
PINKIE PIE: That isn`t a party cannon?
APPLEJACK: Nope, ain`t a party cannon, Pinkie.
DURGEN MADHAMMER: Good shot, do you want a job?

(For those that aren`t familliar with the tabletop game Warmachine, the steam powered robot is a Ghordson Driller warjack. Warjacks have an artificial intelligence, but they can also can receive commands using magic (in the game by specialised sorcerrers callet warcasters), that is what Twilight is doing. Durgen Madhammer is a mercenary warcaster who likes explosive weapons and spells. The event on my picture happended before he became a mercenary, when he worked in mines controlling warjacks and blasting tunnels. After several mishaps in the mines and deaths of dwarfs he left the mines.)
