This is
very minor things and just an extra tip for more realism because now I don't know how long you've been photoshopping for and as I said earlier the concept and colors and overall image is already good
.
For things surrounded by grass we usually use mask and fade out parts that is behind grass, right? This is the most common and basic and fastest way we go about this manner. But try this technique out and mix around with the brush settings, I think you will like the outcome aswell. This can be used for realistic fur creation also.
To the point: choose grass brush, the general brush that comes with photoshop, the 3 grass blades. Go to
brush settings >
shape dynamics and tweak around with the angle jitter so that the blades angles is to your liking. Deactivate
color dynamics since it changes the color tones on each click. Then try around with the spacing for the brush to get the spacing you want and the most accurate. Now use this brush on 100% opacity and brush around the objects on the mask to get a more realistic approach to things laying in the grass.
Practice or try around with different color corrections (
color balance mostly used) and levels for the objects you add to a photo to make them blend it just a bit more.
But once again, good work and keep going. Do you have a deviantart account where you upload your art so I can see more?
