I mostly work with UTAU and VOCALOID for my music and for my original songs I try to make them sing in Spanish and English.
All the art in my videos has been drawn by me, unless otherwise stated in the video's comment. :)
I'm the creator and voicer of the UTAUloid Camila Melodía. You can download her voicebank here:

The blog also contains some tutorials for UTAU beginners.
