Great work and well presented. Only the outlining of the clouds in the orange sky looks poor.

Lovely background work here.

 The grass in the top left one is phenomenal. The one on the top right and the two on the top left are my favorites. I like the cave on the bottom left a lot, but the crystals somewhat break the style, I think. The underwater one seems the most unfinished.

Nice backgrounds!

beautiful landscapes

 you could have uploaded different pieces. This is really great but the bot right one isnt finished yet

Great colors, I especially like desert and volcanic level!

 Nicely done!

Those are beautiful, too many colors and all...do you or will you have a link to the game?

Great stuff.

 Awesome!
