[2] Bernadette McNulty of The Guardian gave the album three stars out of five, calling it "melancholy but slit", and saying that "vocalist Tom Higham deploys his requisite falsetto sparingly, but the surfeit of emotion and tranquillity [sic] flattens their musical landscape".

noted that "Aquilo captivate most when they vary the tempo and instrumentation within their songs, and they do it often enough to make Silhouettes a strong debut overall".

Although sometimes the journey gets bumpy, and Aquilo lose their way to sleepy filler, they always manage to find their way back to the dreamy, lush pop and rich electronic tapestries that makes part of this record such a triumph".

[4] Mixmag crew gave to the album an average of eight out of ten and wrote that "Lancaster duo Ben Fletcher and Tom Higham create spellbinding and atmospheric pop that’s perfect for wintry church concerts.
