It's wierd, the preview didn't catch my eye. It was only until I saw it so high up in the weekly showcase that I decided view this mockup. I'm glad I did. This is so fresh and different, thanks.

 great lighting!

 Nice work on the lighting! love it!

Damn, those mountains are just awesome.

This is fantastic. It would definately be a playable sidescroller.

yeah, very very good.

Awesome, but if you gave the players/characters more contrast from the background, it'll definitely help.

I like the dino bones/skellies underground. Some games show different strata levels showing the bones down low, so like grass>cliffs>dirt 1>dirt 2, etc. Could work nicely here.

The characters are a little hard to read, especially the main one, because of the use of green and brown which is similar to the bg.

Don't like that 3 color dither banding in the sky, you can afford to spend some more colors to make it look nice, or even that solid blue would look good with aa on the mountains. Just some thoughts.

 I like the mountains and power lines a lot. I'm not sure about the use of dithering, however - it seems excessive in some places and lacking in others (e.g. the shading on the clouds). Nice colors though! I like the moon too, and the highlights on the trees.

 It'll be an adventure shooter - like Flashback, but more adventure and quest/puzzles. I hope it will be :D

Thanks for comment.

So many concepts and mockups... give us the game! ;)

Nice atmosphere :) Would be good as and adventure game (surroundings resemble those from "Alan Wake"), but from what we can see - it would probably be a shooter, right?
