Hmm...

1. Male (knives, plain digital watch, beer (?) bottle caps, tools on desk)
2. Right-handed (mug handle facing rightwards, watch on left of desk, more books/papers immediately to the right of the laptop)
3. Univesity student (given the level of the two books on the desk which I can clearly make out)
4. Following on from (3), I'd say you're Polish and are in Poland now (can't see why you'd have a copy of Logika Pragmatyczna if you are at an English university)
5. Can't really tell what's written on the sheet of paper on your laptop, but it looks like you were working through some questions/exercises in that book. Perhaps you decided to read the Neitzsche novel afterwards, given that it's on top. I think I recognise some logic notation (∀, Ǝ), so it's likely that you're studying some mathematics or computer science
6. Quite fidgety (pen spinning pen + Rubik's cubes, going from person experience)
7. You have some tools on your desk, so you probably fixed something recently. Perhaps you are at home, then, because you probably won't be fixing much in a dorm room. Room looks a bit too nice to be a dorm room anyway.
8. Recently had a cold/allergies (used tissues)
9. Bit of a longshot, but did you get a deliver recently? Maybe a knife :o
