Approximate Measurement

Okay,so I approximately compared three OCs of mine from different stories I write(two ,together with friends) ,so I could settle for my own self and for you how tall could be Calles.
So,I took a 9-floor-building,and compared with Calles. So everyone and everything on the picture is more compared to Calles.
-KREON[shadowofj.deviantart.com/art/T… ,who is one of my most complex Dragon character OC,from the story New Dimension(which I write with friends,with includes Hina-Monoko toox) ) is the tallest of all. He'S the Great Fire Dragon. All you have to know about him,that he's enormous,cruel,charismatic and a noble dragon and the main antagonist. He has the form of the typical Western dragon.
-TRENT[shadowofj.deviantart.com/art/T… , who is my OC from the story Roseland(which I also write with Hina-Monoko,and friends) ,is a normal sized human being(with special abilities-just look at his tattoo-) is around 1,78 cm(around 5'9),is that tall compared to Calles,how you can see on the picture.
-CALLES ,who is my OC for ,it can be seen,that he's not a big gigantic beast,at least not so tall. Like I wrote on previous stories,he can fit in a wider corridor,because he has a "skinny" body(well,at least to Kreon,he's more skinnier,probably thanked to their age difference too),but his problem is that he has big,wide wings. Compared to Kreon,his wings are wider and bigger,than his own body,also his tail is longer than usually should be. And there it begins.The huge differences between pirate-dragons and classical Western dragons,but I will tell you more about this in another project I'm working on \o/
So my conclusion is,that I don't really like creating colossal dragons,who're like bigger than the Globe itself. I find that very exagerating.And how they even fit into a cave,then?And how do they fight with people,if they're so tall,they can't even see the ant-like humans? So yeah,I think this size is big enough.

Well,I hope this will be a great proof and also a great thing to know about Calles so far. Thank you for passing by,and looking at the crappy picture I drew!
