Dark Fantasy Visual Asset Package for Author Brand

Hi! I’m looking for a designer to create a reusable visual asset package for my dark fantasy author brand and novel. By visual package, I mean individual elements that I can later import into the free versions of Canva and/or CapCut, place over different backgrounds, combine, remove, and reuse in future Reels and posts. I was thinking of around 6 base backgrounds + 3–4 reusable overlays. By overlays, I’m imagining things like feathers, particles, subtle light/glow, fog/mist, etc. I would also need two complementary fonts: one for hooks/titles and another for regular text and CTAs. The fonts should be available for commercial use. These are examples rather than strict requirements. I don’t have much graphic-design experience, so it’s possible I’m overthinking the structure and that a different combination of static/animated backgrounds and overlays would work better. I’d appreciate your advice on what would make the package versatile and easy for me to use without creating unnecessary assets. I don’t need detailed fantasy illustrations or elaborate magical scenery. I’m looking for something simple, elegant, dark and atmospheric, with enough space for text, quotes, book covers and other content. I would prefer not to use generative AI. If AI would be used as a minor part of the workflow, please let me know beforehand what it would be used for. I don’t want the final visual identity or its main assets to consist of AI-generated artwork. I’ve attached my book cover and examples from some of my recent posts as visual references. They’re there to communicate the atmosphere and general direction. The main thing I’m looking for is a cohesive, reusable visual system that I can continue using myself without needing a designer every time I want to make a Reel or post.
