Not bad! Reminds me a little of the Apocalypse World system where you roll 2d6 to accomplish something. On a 6 and below, you fail. Simple as that. 7-9 is a weak success. You might only accomplish part of your goal, or you might accomplish it and suffer some negative consequence. A 10+ is a strong success. You reach your goal and maybe even go above and beyond! Stuff like augmentations and traits can add +1 or +2 to your roll, and naturally some things can make you take -1 or -2 to a roll as well.
