Perhaps true you two, as I start to love 30mm more ad more myself, but recognize also that those are mostly destined to male, not to women, not so attracted by soldiers, battles, armies, uniforms, battles ... it is a macho world, and larger size flats have attracted many female painters also during le past 20 years (Cesario, Elordi, Lebrun, Meyer, ...), young juniors and a generation of painters less obsesses by wars, weapon and armies, but art, fantasy, fantastic, on the same way that canvas and wood painting before the Renaissance was dedicated only to religious subjects, than portraits and civil life, then modern subjects of all kinds = we call this evolution ... Busts are sometimes disregarded, not for their size, but difficulty to be painted correctly by painters used to small sizes, where a face is most of the time simplified.
And remarkable painters appeared and have even more talent that the thousands of large dioramas of battles (two sided) where each soldier was roughly painted to have a mass effect on the historical representation. I don't deny the excellent painters also of these periods, but such artistic representation is not exclusive.
On the same way we cannot state that only Historex and Metal Models 54mm historical figures are the only single representations of the world of the figurines ... This would reduce the world of figurines to a small part of what it has become today.
It is up to everyone to find his/her pleasure and satisfaction with a hobby that give us joy, friendship, passion, and not in a context (I hope) of money, profit, jealousy and conflicts.
Final words are HAVE FUN, KEEP ENJOYING this hobby, it is for ourselves first.....
