Hello there! I think your blog looks great! But, just so you can make it more appealing to the everyday reader, I would suggest changing your theme to something with a little more color to make it more inviting for the reader (i.e. Quintus, Mystique, Selecta, etc). Also, you may want to expand to your about page. People like to know whose stuff their reading and why they should read it.
As far as the content goes, I think it is very interesting, being that I am into photography myself. Something optional that you could do to encourage others to continue reading is add a story here and there, whether it's about one of the photos themselves or about your travels. Take you readers with you wherever you go. :)
I hope that this was helpful to you!
