This was made for myself. It's been ordered from StreetShirts.

If anybody wants me to post pictures of the shirt after it's been printed I can!
I've got no idea what the quality is like from them, but they have soooo many positive reviews.

People on Instagram have been asking me if I would do shirt commissions like this?
I dunno man. I mean I spent 8 hours on this. It would be pretty dang expensive.
Probably something around the £30 mark. But I won't be open for them yet.

I hope you guys like it though!! <3
