My very first Con :D

So, saturday, i went to my very first Con, Torucon, here in trondheim, and it was AMAZING! God, there were some fantastic cosplayers there, with everything
from Circe Lannister to Commander Shepard! I was there with a whole gang, where i was Gold from pokemon GSC, one of my friends were Fionna, while the other was Marceline!
I swear, they had fantastic costumes, and really fit their parts! I also went with a griffindoor student, a Jack Sparrow and a couple of Volcaloids

Anyways, all the awesome cosplays there really made me wanna make my own great cosplay (the gold one was pretty easy) So, i was wondering if you guys had any suggestions?
I suppose i should be someone fitting my appearance (I'm really tall, and on the heavy side) so all yaoi fancy guys are out of the question

Anyways, do you guys have any suggestions? they would be greatly appreciated!
