Nice!

This is an awesome Landscape.

Nice

It's nice,
not to difficult, but still very cool

Somewhat cool.

Really love this one, but it looks simple, and the detail is cool and everything but add some trees or something.

It might be cool!

I gotta say that i like this!

Not bad

Quite simple, but OK.

Slightly gradient sky colour would help, I would remove the black lines on the edge of the hills and I can't make out what the dark green is on the left. Kinda like a cross between a tree and green smoke.

I imagine you could do better if you put your mind to it- maybe you should try sometime, just to have one good thing on your art profile.
