Fiction Adaptation- Script Feedback

After handing in the script last week today we received our feedback today in which we were able to see what we can improve in the script.
The feedback goes along the lines that;

• A well presented and carefully thought out script with some nice shot and action description. 
• Character is well established at the top and the memorial service is nicely paced. 
• My only issue is that the ending feels a bit of an anti-climax - the narrative of the old man's story doesn't seem to go anywhere - this is a shame.
• Would like to see some sort of development and arc to his story - otherwise he is not really adding anything - go back to basics - what does he represent? Make sure this comes through in his story and character. 
•  Otherwise it is tightly scripted piece with a lot of potential - simple but effective. 

My character in the film represents some one who is morning through the years but is not doing so in an open and dramatic way he is playing it down as he is a military man and has been trained for this. I feel like his story is going somewhere but is better seen in the film in the way he changes his clothes in respect and puts the poppy on proudly.
