Hi! Welcome to Steemit! I am also kinda new here but I can tell you some of the tips some friends gave me and some others that I read from users:

• It is better if you use some picture where we can see your face in the first post.
• Also it is something like a tradition to take a selfie with a page that have the logo from the website, your user written down and the date you are joining, that helps user to trust more that you are a real person. you can look at some examples in the #introduceyourself tag in the news section. (you can also add this tag to your post so more people can see it, it is specially for the first post of everyone so you can get more support, but use it only in the first one :) )
• Other thing is to always write down the source of the pictures, so you have no problem with copyright. Eeven if it was taken by you it is nice to write "This pictures were taken by me, with X camera".
  I hope that this will be of some use for you, and that it doesn't upsets you, it is good intended so you will have a better time here!. I really liked your picture and you seem like a person that can bring interest thing to the community, so I hope to see more of your post soon!
