I generally think self-promotion is a good thing. How else are folks supposed to be able to find you without a little bit of promotion? I never understand those who frown against it. I'd much prefer individuals promoting themselves than sitting through the advertising efforts of massive corporations.
Anyway, overall, I'd say the video was enjoyable. I appreciate the inclusion of humor throughout.
Just a critique note, for what it's worth: in my opinion, the video would have been helped with a bit more organization. Instead of "most impressive," I think you'd better with something like "top six most impressive spells!" Or however many you listed. Along with a count down. It helps the audience to know where they are in the list. To have a sense of what's coming, and it allows them to have a little fun by trying to predict what's next.

One of my favorite spells would have to be summoning the Cheeky Quasit. I really love that Larian included the option to get Shovel permanently as a familiar.
