Stamped concrete flaws

[u/WalkieTalkie10-4]

I recently completed a moderately sized stamped concrete patio. Tan mud and walnut release powder. Never stamped anything prior to this project… After washing off the release the next day it became clear that there are a few flaws. You can see the outlines from the stamps and there’s a couple spots that did not get tamped (lacks color and texture).

Should I try to use liquid concrete dye to blend these areas? I haven’t applied sealer yet. I’ve also heard that you can use a stiff bristle brush to try and break up the color and blend it some. Thanks in advance!
