Whew, got all the drawings done, scanned them in and now well into the process of putting it altogether. With regards to music, my initial thoughts of a slow paced track was not quite cutting it, so I've settled on a faster paced track which I think works well in driving the tension before the finale.
Here is a second version of my animatic to experiment with sound, it also includes the brief opening frames of my animation as I've still working on it.
With some finer tweaks as well as more sound effects should help round out the sound as a whole. Eager to hear your thoughts.
