Yes, you should be good! Like Ken Teutsch said, if you’re not doing lots of scaling, you should be good to go.
Also, if your artist isn’t familiar with prep for AE, make sure that they don’t save everything as CMYK! I have had that happen with artists before. During the good ol’ FinalCut Pro days, CMYK PSDs imported with super strange color profiles. Pretty psychedelic-looking!
