Very nice. I think you should created darker shadows because the depth isn't quite there just yet. Look at the "V", at the bottom where light should be blocked you can clearly see a light patch. I would fix that. make the shadows darker and also making the front face of the text darker too. With the green tree in the background. The transition from dark to light is too sudden and could be better.
That looks really good. I'm surprised you can do that in that amount of time, I probably couldn't even do it in a day, seeing I don't know how to do it
