Design critique and five master carousel templates

Merlin Studio drafts branded Instagram carousels from templates, and the difference between good and generic lives in spacing, type and hierarchy. We need a designer with real taste to look at the work and raise the bar. You review a set of 20 existing carousel templates, say plainly what works and what does not, then redraw the five that matter most as master templates. Deliverable: an annotated critique, plus five master templates in Figma at 1080 by 1440 with cover and inner slide variants and clear rules for logo, type scale and margins. Done means: the five templates work with a sample of very different brands, and a developer can rebuild them from the file without asking questions. Must have: Figma, a portfolio of social carousels or editorial layouts, strong typography and grid skills. Nice to have: HTML and CSS, multi-brand design systems.
