I love making UTAUs as well, and its great to know that you care about my interest in your UTAUs! Suzuki Hoshi's V4 voicebank is a huge improvement from his V1 voicebank, and is extremely dynamic in comparison! Aside from making covers with my own UTAUs, I more importantly love to showcase obscure UTAUs because I want them to be excited to hear their voice being used and appreciated by someone else.
