First, let me congratulate you on this fantastic piece. You did a wonderful job with this design. I love the textures, colours and the detail you placed in it. I can tell you put some thought into this. I love it! Good luck!
I like how the contrast is subtle but poignant, without slamming us in the face with their differences. There's a lot of cool symbolic work here, and the delicate lines are absolutely gorgeous. The tiny hikers on the mountain are a nice touch, too. Good luck in the contest!
