Your picture isn't bad, but its presentation is lackluster. Be wary of misrepresenting your image - no matter how much work you put into it, if it's not properly optimized, a traditional image that isn't properly transferred into the digital format will look worse than it could, which is a shame to the work put into the image. I've created a video tutorial on addressing this issue, feel free to check it out on youtube (/watch?v=gJrgnxKehso). Keep up the effort and thanks for sharing :)
