It's a good first attempt but a lot needs to be worked on. Jack mentioned blending and what he means by that is you want the text to fit in with the background. You can do this by adding correct shadowing to the text, using the same or similar gradient map on both layers but don't over do it, you could also add in textures to both the background and the text to help them blend. The color scheme you picked is good but the improper lighting is ruining it, try looking for some good light rooms on YouTube and add appropriate gradient maps to the text to achieve good lighting. Keep at it, hope to see a second attempt.
