If I were you, I'd be careful about mixing FR/LG sprites with R/S/E sprites. The styles are quite different, and it sticks out quite a lot. The scratchs sprites also are fairly bad - this is, however, just my opinion.
On the upside, the plot is unique and actually somewhat interesting. Keep up the good work, but don't forget to make sure the grammar and dialogue within your game is of high quality; it's one of the easiest things to forget, but it really helps make a game look more professional.
