I don't have much experience drawing men, but I will give it a try.
I'm sorry but Miyabi has to be my test subject. It can't help that some of Holostar is really similar to a girl and I think I don't have enough skill for that.
I also don't know much of Holostar either so this is going to be a tough work and probably not going to end well. But I must complete this work. The boys need more love and I must help in any possible way even my help is rather futile.
