I am sure someone else or Llamabeast himself will be able to help get the map uploaded. But if you decide to go for an alternative here are some choices already on LlamaServer.
Your map:
Sovarinthy: 233 land + 26 Sea (Wrap)
Possibles:
Alexander 247 Land + 43 Sea (Wrap). There are two water nations so extra sea is not bad perhaps?
Mistletoe 222 Land + 30 Sea (Wrap). A new 'random' set up for a game a week or two ago with very similar dimentions to yours.
None Wraps:
Glory of God Multiplayer: 227 land + 47 Sea. Very popular map.
AomOrc 3.01: 227 land + 32 Sea. If you like unusual graphic maps!
Orania has perhaps too little sea (just 20) but is a commonly used wrap about the same size. Or you could squeeze us all in to Cradle
