I agree with what most are already saying, you will need to thin your paint to work at lower pressures (for apply detailed work) and because your using a pretty small needle I'd say you might even need to thin a touch for normal pressure of between 25-40psi (for me).
If you were using a .5 needle in your brush you would find the paint can be sprayed directly from bottle (when using createx/faskolor). Ive used .35 that was ok but I think smaller you are going to be struggling without thinning.
Not sure spraying in the room is the greatest idea as those paint particles will be floating around everywhere (not great for you), I'd get a decent mask (if you dont already have one) and find yourself somewhere to paint (spare room with some ventilation for clean air/outside brrrrrr this is where I do it, but its much better in the summer lol).
Any how best of luck and let us all know how you get on.
