yep .. that's true .. thanx a lot for the helpful comment :)

It looks a bit too smooth and "perfect" to me, making the piece a bit uninteresting. Try adding some signs of decay, a crack here and there, more rounded edges on the rocks.

 Thanx for the comment :)
will try to fix these mistakes and glad u liked the stones :)

So big. o_o

Good job on the stones of the walls, especially on the round towers. There's a few little white pixels at the bottom of the bottom left wall that seem to have been missed. I see a few other random mistakes like the middle and right towers on the bottom right wall seem to have the top stones of the wall overlapping onto them.

   Thanks a lot for the very helpful comments .. I ll try to correct these mistakes :)

 Also, the windows on the circular towers are flat instead of rounded.

 The shadows aren't consistant. The castle has them, but the people don't. Also, the walls under the shadow aren't affected by them. 

The soldier's eyes and helmet don't match in perspective.

The bricks on top of the walls aren't shaded, and look like they aren't attatched to the wall.

Some of the red square towers aren't aligned with the walls they're on.

around the red circular towers, the bricks look paper thin.
