You dropped a file link in a channel with "when you have a minute." Two days later you have a restyle of a flow legal already signed, or you have nothing. Both are the same ask: you never said what kind of look you wanted, or what they were allowed to touch.
A designer who is good at the job will generate alternatives. That is the work. Your job is to point that work at the part that is still open.
Three reviews share the word look
Approach. Is this the right shape of flow at all? Twenty minutes, and "do not build this" is in scope.
Craft. Hierarchy, type, empty states, the thing that will feel cheap in a screenshot. Needs time on the surface, not a skim of the product brief.
Ship check. You are shipping Friday and need the obvious breaks called. Fifteen minutes. Saying so is how you avoid a craft pass you cannot take.
Choose the shape in the first sentence. "Craft on the empty state in frame 12, not the information architecture. IA is locked because of the legal sentence on page one."
Write the constraints a cold reader can see
They may not have been in the kickoff. Write as if they were not. Brand rules, the one sentence that cannot move, the viewport you actually care about, the user who is tired and on a phone.
List the alternatives you already tried, one line each. A reviewer who does not have those will spend the hour on your Tuesday.
Mark guesses. "I am assuming the primary task is recover a draft, not start one." If that is wrong, they should say no to the assumption, not restyle the page.
Aim at a reply you can use
The reply is the point. Ask for the one thing that would change the next step: a no on the approach, a marked frame, a sentence you can take to engineering. "Any thoughts" produces a voice note you cannot file.
Default: "If I have not heard by Wednesday 16:00 UTC I will ship the empty state as drawn and we can craft it next train." If you would not ship without them, do not dress that as a deadline.
Send the ask, point at the file
No attachments in the briefing. Link the frame. You approve the words. If they have an account, you need an accepted contact. If they do not, they get email and a page — useful when they are a contractor who is not in your workspace.
Use the name they use. A private nickname does not belong on a review they will read.
If you already argued the flow through with an assistant, connect it and have it list what is locked before you ask anyone to look.
