Sorry, Don't like it, the white on the render, on the visor, really stands out(not the good way), it doesn't exactly look like a reflection or light too much.
And I'm not a fan of the grass brush.
I hope you kind of get the idea of what I'm saying.
I love the bg but the visor looks like it shouldn't be there. However, I should not be criticizing because I cannot do anything close to that in photoshop.
