First Time Trying This...

it looks like you got the design from a kids wall paper but it still look good.

 

I think it would look better if the gradient faded behind the clouds, but that sounds a little hard for a beginner, so good job.

 

I think the fade is a little messy as part of it is going over the clouds. Also, that one streak of the line is out of place, just having that one streak there. As for the design of it, like caboose said, it looks like it's from a kids wall paper. But I guess it's ok for a beginner, just take the cc and practice.

 

How'd ya do it? Layer Mask and Black and white gradient?

 

That's what i thought. Not bad.
