First of all, the art style is beautiful and all of the example MC's look cute.
What I see in illustrations now are girls with slightly different facial features and coloring, some of them flat-chested. But still GIRLS.
See, I'm not sure what exactly is the case, but I'm going to blame the hair. Long hair wasn't a problem for the Red Embrace MC, he still looked like a guy, but here I'd have to stretch my imagination muscles to the limit in order to be able to see any MC as male with options that are available now. If more facial variations are not going to happen, then a short hairstyle would really help. Please make this a goal if everything goes as planned with the Kickstarter?
