This is my Halo spirit landing craft. It's big and bulky and that's about it. My original spirit was blue but I changed it to match my other covenant vehicles. I also added opening doors on both sides and a turret on the Bottom. As well as it grew slightly larger. It's a bit boxy and small sadly. Oh well.
A general front picture. Sorry its so blurry. I want to redo that one but I haven't got the time.
I like your spirit but you got one thing wrong. The spirit let's the troops out via doors that make up the sides. Check out my minifig scale dropship for a small reference. Hope to hear from you in one of my creations soon!
