Yeah, but it looked like a baloon above my tile and the green thing didn't look like grass. It looked like some piece of a background.

and that's a good excuse to not bother blending it?

Look: The bottom of TonchyZ's tile is black. If it would be green I would blend it, if it would be purple, I would blend it. It is black and the top of my tile is black. That is sort of blending. I don't see the problem.
The green stuff could be grass, it could be a green cookie monster, but it was higher and it didn't look like anything rather than a piece of background that became black at the bottom of that tile.

no, I really, truly meant that you should check your monitor brightness, Jakub. Use the eye dropper and you'll see that the left side of the tile above ISN'T black. If you turn up your brightness enough you'll see why people were complaining.

That being said, don't get frustrated. Your tiles are awesome! Keep it up!

Jacob.. Sorry to say but Slothy is right. It is very, very dark but definately green. As he said check it with the eyedropper tool in Photoshop or whatever app your using. Dont fret it too much as it was a hard tile edge to blend, Slothy is just offeriing constructive critism. He's also right that you're doing excellent stuff! Which is probably why he is offering info he wouldn't give to a total novice. His critism of a tile is generally focused by the apparent abilities of the artist. So in your case I would say he thinks alot of your work to focus on a subtle color shift. Keep up the great work.

haha, thanks for being such a good sport, jakub :) Can't wait to see your next tile.
