And that's great. In fact I would say that's one of the most concise ways to look at MOCing, and one that would yield good results, and I assume you've followed this model of building for all of your projects along with your other philosophies.
The snag however, is this
Apparently you didn't get to the last step. And in general... who cares? It still looks like an at-at right? Maybe you'll add it in later, maybe it's still a WIP, maybe you can't figure out how to do it well within your rules and you chose to omit it. All valid points, but whatever the reason someone is going to point it out.
The real problem is the way you limit yourself and end up with a pretty good result, when you could have an amazing result, or even the best result. And then when people point this out to you, you adopt this superior attitude that is extremely obnoxious.
I understand if you don't care enough to make it perfect; hell for me lego is one of my minor hobbies, I bought my first set today in probably 4 months (skiff, amazing figs btw) and if I was in your shoes and had an MOC like this one, I'd have it locked up and never bother with it again. But it seems you updated it recently and that shows to me you do care, and I'd like to see you build something that someone can look to for years as the standard for LEGO AT-AT MOCs or some other such nonsense. You're 90% of the way there.
