How do you beat drawing-room online escape game

Click on the lamp on the lamp on the right in the room with two long lamps and one long couch. There is the orange color pencil. Then fill in the pictures with the circles according to the tiny writing (it looks like a line, that you click on). It should say 450 and have a shape next to it. Fill in the circles according to that shape. Be careful, if you get it wrong, there's no going back. When you are done with all the frames, go back to the room with the door. There will be a frame with an arrow pointing down. The blue color pencil will be there. Open the bottom right drawer of the drawer with the three bottled flowers. Pick up the red color pencil. Click on the left drawer. There will be a note. Pick up the black pen from under the long couch. Then trace the lamp's cord with the black pen. I don't know the rest. Bye bye! Try to figure it out on your own!
