i think it flows very nice for how busy it is. due to your contrast and how you posed the characters. a few things bother me though. first is the leg on the man reaching for the flowers, its too big and if you want if to be foreshortened like the are you need to make the front of the knee face us more. you did a nice job foreshortening the arm though. the right arm on the man reaching for flowers looks a bit stiff and the anatomy is a bit strange. also in that same area you get a little lost, this is due to the fact that everything there is the same value not enough contrast to set it apart. i also dont understand what is happening with the arm of the giant man on the left.
all in all a good piece, i enjoy the different meaning people can pull from this.
The right arm of the protagonist is stiff and the giant soldier has a strange arm position for the same reason: They are chained to each other and the big one tried to pull the hero away. If its drawn better you would see it. My fault :)
The funny hing is that I havent achieved to visualize my first intention: That the man -creates- the flowers
I thought it was like one kind person makeing life while everyone else destroyed it....
The flowers resembled life to me
but come to think of it you're right
