It seems that this series is still a ways off completion and well we cannot blame them, especially since there has been a global pandemic happening. But a scant 14 hours ago the Critical Role Youtube channel did drop this great video which goes into great detail about the work being done on the series.

This video specifically introduces us to  Phil Bourassa, the lead character designer and we get a good solid look at the final character designs. The release of this series cannot come soon enough.
