Hi @batanamatampuhin.

• There were a lot of typos in your article. I would suggest you read your article at least twice before hitting the "post" button.
• I'm not sure if you can use that picture, because, to me, that picture seems copyrighted hence without any permission from the original author, you are forbidden from using such picture. Please refer here if you're not familiar with what I was talking about.
• I would recommend you to elaborate more on your article. Make it a bit longer and make it interesting.
