Create a Twitch or streaming overlay

Design a streaming overlay package for my Twitch channel, NightShiftGaming, that includes a main webcam frame (1920x1080) with 1280x720 safe area, a lower-third alert bar for follower/subscriber messages, a BRB screen with 'Be Right Back — Coffee Break' and a starting soon screen that shows social handles @NightShiftGame and Discord invite link. Deliver PNGs with transparent areas and a version optimized for 1080p stream. I need these files by Thursday for a weekend launch.

Before I upload the overlay to OBS, make sure a distracted viewer immediately sees what matters: enlarge the webcam frame to avoid covering chat, design a clear semi-transparent alert bar that doesn't clash with gameplay, create a small corner area that displays recent follower name, and flag any elements that would hide critical on-screen game HUDs during fast action. Point out collisions with commonly streamed games like Apex or Valorant.

I just did a test stream overlay and during Valorant the killfeed and ability icons sit under my lower-third alert, which will annoy regular viewers and cost me clarity. The streamer collective wants the clean look I promised. I can either shrink the alert bar, move it to the top corner, or make it auto-hide when in active play. Which option balances visibility for alerts with preserving important in-game info, and what implementation is quickest for a solo streamer?

For months I tweak my stream overlays mid-session to fix collisions or to spotlight events, and viewers complain the channel looks unprofessional. I also waste setup time before every stream. What one habit should I adopt so overlays are consistent across games, require fewer live tweaks, and reduce viewer irritations without losing my channel's visual identity?
