By looking at my picture I drew now. You can see the cup from the right was lot wide and taller than the left. That was narrow and short.
However, there was a mistake I did. On the left side of cup the prospection was round and three dimensional, but it looked flat and doesn't see as a cup. Also the top of the cup doesn't look straight.
For now I'm proud what I did and know what my mistake of drawing skill need to improve. For now I need to practice more.
