I’m most concerned that the design looks highly available on the surface, but the actual resilience and security controls are underspecified. You have two frontend EC2s, two app EC2s, ALBs, and RDS, but no Auto Scaling Groups, health-based replacement, NAT gateways, ACM/TLS details, AWS WAF component, or clear multi-AZ subnet placement.
