Good, but lots of improvement is needed
I have just finished watching through the series of your Xionic Madness and I quite like it. The art is good and the ideas are solid. Unfortunately I'm not a complete fit for the targeted audience , however, I think that this would give me a good chance to constructively give a decent review without any biased results so please read this for useful information.
The animation itself is jumpy and tricky to follow. I've always had a keen eye and can understand what is going on most of the time, but I wouldn't be surprised if quite a few other viewers didn't. Try in future to use story boarding or draw out the scene before animating it to get a better idea and a clear-er understanding of what the frame is going to look like. This should dramatically improve the structure of a scene. Also, dont rush new camera angles, such as first person views or heavy shaking into the viewer all the time. This can be distracting and disorientating and a real chore to watch. Think about using layers to add depth to the scene to brake from the traditional character>foreground>background display. This will add much more realism and dramatically improves the ability to watch without questions being asked like "is that a box, or a building?". Although the graphics of the animation had improved significantly since your first animation which is a great sign of improvement, there is still a lot of work to be done.
The music was ok at best, but then again, Im not into that style of music. Lots of the time however, the music completely overpowered the voice and sound effects, drowned out suspense building silence. This wasn't aided with the generic effects used. It didn't really give this a very original feel. Next time, try to use more original sound effects and also try to use silence to give some juxtaposition to the animation. It was always on this "Heavy Metal extacy" and I never felt any suspension, nor emotion. The actual music was relevant to the style of animation you are going for, so I will give you that.
The story isn't very well explained, nor detailed and the reading blocks can be quite hard to focus on with impressive movements and overwhelming gestures going on in the background. Im not entirely into this type of "Shadow the hedgehog" style of animated story telling but im sure those who are, dont really care what the story is about they just want raw violence and futuristic weapons/designs. Which this thoroughly delivers.
Despite being in the Madness category (Pure violence, no real need for decant story), I think that this could have been much more impressive if more emotion and character went into the story. The voice acting really helped and was an improvement to just raw reading blocks. This feature was crying for use from the first episode and it really made it easier to admire the amount of effort you have put in to your characters and backgrounds. Plan ahead with the length of the chapters (this is shown well in the second episode) to keep a structure. In other words, dont display "chapter 1" then show 2-3 shots of someone fighting lasting up to 10 seconds then shoot to "chapter 2". Doing this will make navigation easier for the viewer and also give a rhythmical feeling that helps understand the speed of how your telling the story.
I have given it 6/10 becuase as an animation (and not Xionic Madness) it is strong. It has really nice points with interesting designs, weapons and above all, unique ways to kill people. However, there is a lot of room for improvement concerning camera positioning, sounds/music development and character. The story is generic and titles/names closely follow. I think that most of your audience are within the realms of "Shadow the Hedgehog" style animation so anything black and red with be an automatic 10/10. I hope that 6/10 isn't too discouraging and should help you get a feel to what this truly is and not just "OMG THAT WAS SOO HARDCORE! 10/10". I think you have great potential and try not to think that what your doing is perfect. Try to follow some tips and I wish best of luck in future!
