Hello, thanks for the criticism! I'll comment on the points you had mentioned.
Yes, It got me to that relatively recently that it was indeed weird. I decided to shuffle around some ideas in the comic and change the plot a bit, so story now have some justification to it, stemming from characters actions, that will be revealed a bit further in the plot... Although I'm not sure if it will add plausibility to the situation or will subtract from it even further. X)
Well, Buran was pretty much identical to Space Shuttle too. Laws of physics don't particularly care what planet are you from, so they dictate shape of an object that wants to enter atmosphere and remain in one piece. So I rolled with that, partially because of the aforementioned logic behind the shape, and partially because of my anger about end of the space shuttle program and labeling it a mistake.
Plus, strictly speaking, it is already more effective than human one, since it can accelerate from Jupiter to Earth and back without refueling, and have VTOL and SSTO capabilities.
I was using statistical meaning of the symbol, not mathematical one, I think? Meaning that maximum lifespan of Azinarsi can be anything between infinitely short and infinitely long, since they're digital.
Well, in fact, the longest phase of the drawing is the initial rough sketching, actually. I usually can do line and coloring in two days or less (all hail LazyNezumi Pro, our lord and savior!), so economy there wont achieve any significant reduce of the speed at which I'm making the pages, but it will definitely affect the quality.
