Hello! I'm new here. I draw some GAZ "Tigr" armored vehicles. Problem is - it's not a pixel art, originally. I used vector graphics, later converted it in a bitmap. So quality may suck. Over issues - I never heard of shipbucket rules beforehand (only seen some pictures over the web), so I'm not sure if this drawing correspond to this rules. Anyway, I’ll just leave this here:
Generally, rule is: main models in first column, modifications of that models - to the right from them. Arrows is for the explanation of model genesis in complex cases. Also, I have a pic with better resolution, if someone interested in it.
