Bruno and Clara are aimed at Spanish music professionals and the first Vocaloids aimed at the Spanish culture. They do not incorporate the moe-esque style of the Japanese Vocaloids and their designs are aimed more towards a retrospective European art style.
Bruno has had a backlash based on his illustration, mainly for lacking an anime-like design or referred to as not having the appearance of a Vocaloid, with some going so far as to label him and Clara as "ugly"; however, within the Spanish fandom there have been reports of strong defense from fans of the pair and Vocaloid. The voice type itself; however, has been noted to be appealing in general despite the issues some fans have had for the boxart. The reaction towards the inital artwork had a later impact on future Vocaloids, and it was one of the theories put forward as the reason Yamaha rejected the original non-"anime-esque" design for Avanna.
By March 2012, Bruno and Clara were amongst the least popular of the Vocaloid 3 voicebanks, though together they are more popular then Tonio, neither suprassed his popularity when weighed in seperately.
When the first demos of Bruno were shown, an interesting reaction from English Vocaloid fans was noted that they often did not think Bruno had much clarity. A few Spanish speakers confirm that he had relatively good clarity.
