Not bad, but lots of room for improvement
There is a decent enough plot here, and the artwork is solid if unspectacular, but there is lot that can be improved on.
Firstly include some music! There is a vast source here on Newgrounds in the audio portal if you ever need any, and it would have improved this animation no end. The sound effects were ok, but they don't give any feeling of atmosphere.
Work on your animation skills. There were very few examples of real animation here, with mostly whole objects moving from point A to point B. Try and be a little more ambitious, for example with leg movement, and include a few more moving objects in the backgrounds to give your scenes a bit more life.
Your text based story was solid (barring a few spelling errors- handel...), but it was very slow paced. In particular the animation you used to reveal the text was far too slow, and rather unnecessary. Ideally do away with the text entirely and narrate it with some voice acting- this would immediately improve the whole animation.
Still, some promise here- keep practising and submitting!
