Really not that good.
Chad, Mick, I'm going to be honest with you: most of the things that you two have done after Sixgun Space were pretty disappointing. While I may approve of doing something with your own characters, it doesn't make up for how generic and uninspired this is.
Graphics: I will admit that you have nice colors for this, but the art and animation are inconsistent in quality. Examples:
-Stiff looking walk cycles in contrast with the gestures: I mean, they have some nice poses, but their walk cycles have no real weight or secondary motion.
-Proportion mistakes: Sometimes the characters ears are too high, other times their arms are misproportioned.
In addition, I would also recommend that you cut back on the blur effects a bit. On the other hand, you do have excellent backgrounds. Therefore, I suggest you work on your weaknesses for a bit.
Sound: I may appreciate you getting music from the Audio Portal, but the songs you selected didn't really contribute to anything. Try xenith800, Xarnor, Solus Lunes, Bosa, Obsidian Snow, DJ Harlock/Cross 666 and Waterflame for fitting music. The sound effects were alright considering finding "free-to-use" sound effects that are as good as professionally made ones is not easy. However, the voice acting was just uninspired akin to Tome. They weren't very distinct, nor were they expressive. Plus, by including Rina-Chan in this, you're going to piss off her detractors.
Content: While you do have a nice space setting; the characters and plot in this are just generic. They didn't have much in terms of personality, but at the same time weren't annoying. Plus, there wasn't much in terms of development for something this long. Look, I know not everything needs to be like the Stick Slayer in terms of direction, but for something that doesn't have much in terms of plot; it could have been a bit faster. On the other hand, you do have some nice angle choices.
The Good:
-Nice color selection
-Good backgrounds
-Decent sound effects
-Interesting setting
The Bad:
-Uninspired plot and characters
-Not much in terms of story development.
-The voice acting wasn't very good
-The music didn't really set any mood.
Overall: I have no right to give you a zero since I'm not much better at storywriting either. Here's a six for the effort and I hope you improve on this.
