Well, here it is, my first Halo creation- FINALLY!!
First order of business is I would like to give Stephen Chao a big thank you for posting his Falcon right as I was building my and for giving me the ideas for the entire back section (including the tail), the engines and wings, the entire top part, and a little of the front. THANK YOU!!!
Secondly, I would like to ask if anyone has found the perfect widow for the Falcon becasue I tried a few different windows and I don't think lego has come out with the perfect one yet. I tried the Life On Mars (remember that one- I was really young when that came out) alien winshield, but that did not work out. Ther is a picture of the winshield at the bottom if you don't remember. So I finally had to go with the X-wing window which I think is too boxish.
Lastly, some differences that you may dotice is that I did not add on a "chin mounted gun" (that's what i call it). You are right. When I was constructing it it didn't look as good as it does now so I just took it off, add the two miniguns on the top, and called it good. Also my Falcon can fit six men including the pilot which I thought was pretty good considering it's Lego.
