Keep working with tutorials i can see that you have a lot to improve upon, but don't be discourages, everyone starts somewhere :] you did a good job keeping the effects off the render, but you've still altered it soo much that its lost some appeal the colors are very close, green and yellow-green aren't going to create much of a good combination in most cases. the only other thing that stands out is the large amount of dead space where you've put your text. Keep on practicing and keep on posting your work, were all about helping out around here ^_^
Fix the lower contrast/brightness and decrease the sharpness and it'd improve a lot. Keep working on it
Seems oversharpened at a few parts, thats why the render is not in the foreground / the focal point. Blur the effects more if you want to have em as a / in the background.
