Giant professor Birch 1 (Lineart) (Patreon)

Hello everyone! Finally here is the first of the 3 drawings for professor Birch who won last month's poll, I know this has been a slow month but it's because I have been fighting a lot with this sequence. 

Yes, this time I'm making a macro growth sequence! This is only the beggining so get ready because I'm making him HUGE!
