Dear yoot zekkin.
It may have already been brought to light, that the community is unsatisfied with the current state of this tenkeyless board.
Their main concerns is the engravings and name. They feel as if you are simply using it as a way to capitalize off the current popularity of the v-tuber k-pop organization known as Hololive red velvet. I, to some extend, agree with this.
While I do believe it is acceptable to make a board inspired by your favorite v-tubers idols, doing so consecutively without any clear link between the board and the v-tuber idols will arouse suspicion as to whether you are truly doing this due to passion for the keyboard community and the v-tuber idols your board is representing, or simply doing it for your own gain.
Although I do see the idea of making a series of v-tuber k-pop inspired keyboards, I would highly advise you to reconsider the direction the design of this board is heading in. Either you should directly link it to an v-tuber idol with clean engravings, or remove any current resemblance, and simply run the board as a standalone group-buy.
Either way, I do believe the board has the potential to turn out well.
Best of luck.
