It's the map of the UK! (look closely and compare with google maps if you need to)
Ireland was the more difficult here, Arthur and Wales fit in perfectly though XD; but the Irish are just kinda.. floating.
Well this is my impression of what I believe Arthur's brothers to look like (oh Scotland turned out perfectly <3)
Obviously unfinished, will colour it eventually.
You have no idea how hard it is to make a person fit into the shape of an island, especially when it's Scotland and has loads of wee random islands surrounding them.
Yes, that's a leprechaun in Ireland and a sheep in Wales (cause there's more sheep than people in Wales!)
Um, I'll give them names.
Wales: Gwyn Nevett
Scotland: Duncan [FINDLAY] xD
Northern Ireland: Patrick O'Neil
Republic of Ireland: Killian O'Neil

Also my friend mentioned that you could see a bit of France in the corner of the map of the UK when I was looking for reference and told me to draw him in... That really faint line in the corner... Well Francis is in a fabulous place, right next to Arthur's arse, oh, fun times.
NOTE where London is 8D
