You use the two tools that i love the most and have mastered them!!! Amazing!!!! I am inspired to say the least, I also quite enjoy your anime style... I have my own style which is more realistic with regards to the face and i would like to develop an anime-esc style. Time to get to work i guess D
as for the the issue i read on the shape being less than optimal for shipping, here's the biggest thing to remember.... IT'S FANTASY, ITS NOT REAL... just enjoy the fact that it looks really cool and will more than likely make a neat cut scene element in a game/ space fight
Some thoughts: I like that you have container ships. It's a practical thing that will probably never be gotten rid of. Your container shape is utterly impractical and pointlessly pseudofuturistic. Containers are rectangular simply for packing efficiency. A non rectangular shape like yours would always be undesirable for the amount of wasted space inside it once you're done packing. Also you could store the containers with your design more efficiently by having the rows at half stagger so one row nest on top of the one underneath. Shipping will always be a practical business.
The customer gave the dimensions of width \ height containers. I did everything in order. Everything else - not my problem. But in any case, I believe that for a given universe, such a container at the time. Comparison of fantastic games RTS (TS) of the genre with real life - more than not correct.
