Story ideas for any gene of writing and critique my current idea?

hmmm...i like the ww1 premise but i think your going a lil too dark. i personally think hes kid should already be born and be at least 3 to 5 makes for a much closer bond. i think you should have the mother die of an illness or some sort of tragedy but keep the kid alive. have the kid get taken into foster care, have the soldier realize this which gives him a great incentive for returning safely which will give the reader a way to sympathize for him, it'll keep the reader rooting for the main character...that's just a blueprint there's plenty more u can do with this...if u need any more help just contact me through here. hope this could help :).
