Cosplay Ideas - MCM Comic Con London

I'm going to London comic con this year to see the Magnus Protocol panel and hopefully meet the guys from Rusty Quill !!!

It's my first time cosplaying and i'm still not sure who to go as.

My two cosplay ideas are: 1 - Gerard Keay. He's always been my favourite character and I already have plenty of fitting clothes in my wardrobe. Something all black, with boots and lots of chains and other jewelry. Fake eye tattoos and I could probably find an old leather book from a charity shop.

2 - Breekon and Hope. Plain black overalls with some writing on the back that says Breekon and Hope Deliveries. I also have some styrofoam that I can paint to look like the coffin.

What do you guys think? I'd really appreciate some tips or feedback. :)
