The lightning or whatever it is on the bottom one is just a pain to look at. The colors are way pastel to look good on any nature scene, and the floating color blobs aren't even blobs but rather 1-2 pixel mess sharpened into oblivion
Uhm, well ; not really a fan of these but i'm going to post my opinion anyway.
It does look pretty neat but there is to much pastel in it, and it doesn't fit with nature pretty well so to say, good for starters though >3
