For the most part, Makoto cycled through a small number of glamours when doing his work on the streets of Venera, attempting to look as much like a nondescript young Veneran as possible. Though one could make a criticism that the glamour he used by far the most often was just that of himself, as he had appeared as a human, for the relative ease of the glamour, and that included when both investigating and capturing one of the marks on the hit list with Gen as well as when he and J apprehended Barnaby. The former he did earlier in the week and in broad daylight (though he was trying a bit more to blend in), though the latter was later on and very early in the morning.

When confronting Liem and Hayame, however, he did not use a glamour (purely for the Drama of the moment). Given that this was later on in the event and occurred at dusk, there were essentially no passersby on the street and visibility was somewhat limited, though it's entirely possible he could have been seen from nearby buildings.

So maybe he will consider using a different glamour, if he ever has to go back to Venera...
