A project I have been working on

So for the last 4 years I have been work on my project/ story (Started it off to prove myself wrong and grew from their). It follows a group of marines in a battalion and their story throughout the covenant war I wanted to focus on the fact that even if the marines secured victory on the ground that doesn’t amount to much when the covenant can destroy all their hard work from orbit, to compound this you have active insurrectionist movement undermining the UNSC which the marines have to deal with.
I split it into three parts The beginning of the covenant war (Marines), then about halfway through (ODST) and the final years of the war (ODST/ high risk) and have completed the initial frame work (Overviews of what happens and Key dialog) its about 100,000 words long.
However I have gotten to the point where I would love some feed back but have no idea where to send it I am hopping someone here could point me in the right direction as to where to get some feed back.

Thank you for any input

PS Would love to send it to 343 but realize that this is pipe dream
