Very good looking vid with some great touches, shame about the song Know nothing about filming but I would think the difficult thing to do is not use to many techniques. As you are learning I would say less is probably more, if you get my drift. Easy to get carried away, and include, all the new things you have learnt and include in one video. This could take away from the over all feel and make it a bit gimmicky. Once again though I must say I'm enjoying your work and the journey.
