I think the 'problem' may be the unnatural uniformity that is bound to occur when using this technique to create grass. Every 'blade' of grass is going to be pointing in exactly the same direction... straight up. I attempted to soften this with a bit of painting in the foreground, but was afraid of over-doing it... I'm still getting used to using Painter and Photoshop with my new Wacom tablet. Also, I think a few fluffy dandelions scattered about would've added a little more realism to the scene... but I didn't think of that until after I posted this. Might change it, but, again I worry about over-working just about everything I do.
