As above comments. Videos always do well with marketing and so its important to make them stand out. Even though its nicely done, that would be my problem with it.......its nicely done,,,,,,,not amazing or great. I would agree on increasing the size of the pictures used in the slide show and to focus on a quality photo which shows off your best work, perhaps with the stark contrast of before and after.
Plain text is great, as it stands the message out, but perhaps a different font.
Sorry kno it sounds a little critical, but hopefully its constructive and not negative.
