to give a more detailed reply from what TDitH said, there's much room for improvement and being a veteran article writer from retrojunk since 2007, i would recommend these steps:
1. study on article formatting. provide at least two or three long paragraphs before adding pictures, this will provide a nice, lengthy article and won't make it feel short. it's best to pull in readers by going more into detail with a specific part of an article you're writing about.
2. proper grammar, punctuation and spelling is key for an appealing article to your viewers. i know i'm not doing the same for my forum posts, but articles are far more important and they actually matter on this.
3. make sure you properly size your pictures in with the formatting of the article, the preview button is there for a reason and is to show an example of how the pictures will look after the article is published.
you could use any of my articles as an example of how formatting as well as picture placement should look. i see you've already written a few articles and i'm sure you have the potential to make your future articles stand out more.
