Not bad.
Really. The GUI looks a bit dull, I must say. I think you need to make it a bit more colorful.
Oh wait, I changed my opinion on the GUI. It's excellent and fits BL very well. I didn't notice that you were making a replication of the regular DayZ inventory GUI.
ill get a picture of it while in-game
Good work!
Now you just need to make it function :P
