Harry, you spent 5 hours working on the mask? That would make me crazy. There comes a point where you have to walk away from it an come back. I bet you were to tired to work. It is like the math problem that you cannot get right because it is late and you need sleep. Go to bed and when you get up in the morning, you are able to answer the question.
Because you have trie to draw a circle. You have to move the pencil from left to right and back pressing when the coin is under it.The area od pencilling should be bigger.Try at another place.
Great Harry.That's it. Try it again at the next place.Don't be limited with the pencil moving to the circle shape of the coin. Now press the pencil not so strong like above.
I see it is the paper fault. It should be thinner one.But OK. You got it.
Harry in the same way you can try to find the shapes of the frame windows. Stick a strip of tape to the conopy and use your pencil like for the coin.Maybe not so strongpressing but these raised lines on the conopy should appear.Try to do that. And show me the effect.
