nice colors and blending.... lighting could use some work.... it is also incredibly - flat - try using the blur and sharpen tool to add some depth
Maybe put some blur on the water right behind the thing she is sitting on so it looks further away...etc...do a bit of experimental blurring and you'll see.
See, you can already start to see the depth behind the rock/tree/whatever it is she is sitting on. Good job.
great job ! looks really nice. maybe blur that last tree right in the middle of the background so it doesn't stand out so much and you gots an awsswesome tag !
Leave it at #1. The curved perspective, and wonderful water color is great without any fake looking blur.
