Where is my mind?

Trying out some invisibility tactics, this edit took quite a while.
In other news I've got a maths exam tomorrow, here's hoping that won't be too awful.
By the way, does anyone have any tips about how to not lose clarity in photos once you get to the editing stage? I've always shot in the RAW format and find once I've converted to JPEG or something similar, the photo has usually decreased in quality. Any advice would be much appreciated, I hope 2016 so far has been good to you all.
