This is being underrated by people, it's certainly much better than a mid-five. I think this is mainly due to the photo. Maybe you should look at your lighting, the green parts look great but the brown parts are difficult to make out. The background is also a little jarring, try re-posting a picture with the original background. As I said before - the green is excellent (especially considering it's one of your first miniatures) so don't be disheartened by the low score, you've definitely made a promising start.
