I pray all is well. I came across these resources that I thought folks may be interested in. The first is a post about putting together quality comic-book trailers for free, and the other is a website specializing in a unique approach to logo design, among other types of designs.
And as an aside, I encourage you to join the Christian-Comics group on FB if you haven't yet. Great fellowship and we group chat consistently.
Be blessed and continue to create!
