Even though many people may not like it for having an older man as the main protagonist, I actually really like how it looks; it clearly has Doctor Bones’ style. As long as it keeps a consistent rhythm and uses similar types of fun situations for the scenes without forcing anything, it seems like a project worth following in future updates.
My only suggestion would be to give the girls a bit more personality, because I feel they not only look too similar, but also act too similarly. Giving them more distinct traits would help make each girl feel unique.
