This is lovely! I really appreciate breaking out saving throws and movement speeds, and you've done a similar "defenses" area to what I've tried in my designs, and I love the extra rows for actions in combat, plus the maneuver formatting.
The only thing I'd call out is the positioning of the proficiency bonus. Skill checks in A5E tend to involve referencing an ability, then scanning the skill list to determine if proficiency and/or an expertise applies. I've found putting proficiency as close as possible the skills themselves makes it easier for a player to scan from "Charisma (+2), Persuasion (+3) uh, does my Dealmaking specialty apply? (+1d4)."
I've actually set my sheet up to write out proficiency repeatedly for each skill it applies to, which might be overkill but does seem to slightly speed up play. Some means of relocating proficiency so the scan isn't "top of sheet->middle of sheet->top of sheet again" would help, maybe even just moving proficiency below ability scores, or duplicating it near skills.
