Whoa! Thank you so much for playing this game, and especially trying to play it in another language! I hope it wasn't too much of a difficult experience or anything! But it does sound like you had a good time!
Yes, of course! I don't mind if you want to draw your own character or even other characters with Milo, in fact, I very much encourage any type of fanart or fancreation! I really like fanart hahaha.
