I'll try that next time i do somtin like that thank you.

Still a little flat. Try practicing some depth by picking better angles for your pieces.

For example, in this piece, if you instead of drawing head-on you picked a shallower angle, say a 60º-45° angle instead of 90º (which is directly above, like you drew), you'd have to draw some height on the device, the buttons, the screen, etc. That would help the piece a lot.

But keep drawing, and keep studying other people's work. You'll get better if you practice and force yourself in the right direction. :)
