You're good at this, no doubt about it. But there are some things you need to work on. For example, the music. You've selected good music for the series, but you must make it fade away, not just stop abruptly. That, and make some nice effects for the endings. The last episode ended so suddenly i couldn't believe it. Keep these things in mind when making the next episode. But except for this, the series are very good, keep it up!
