The 'Gumtree sites' Words arent readable. A logo should be of all things Outright, readable and elaborate.
I love the graphic, but perhaps you could use a bolder font to acompany it? The current one looks a little bit lost and doesn't really stand out much or attach itself to the design so well. 2c
The title and the logo looks good and attractive but the background green color looks high in contrast, try to decrease its contrast a little..
