I try to do the same thing as "Heavenly"...I see a neat looking sky and attempt to photograph it. But those powerlines are right there...so what do I do? I try to incorporate it in some fashion. Does it ever work? NO. So, my comment is to find a different position to shoot from or a whole different location and wait for another one of these beautiful skies to happen.
The "Old Barn" one is mis-titled...it should be "Bush in Front of an Old Barn"...the bush is on a "RoT" line and in focus...but the lighting is flat which most likely means the sun was at your back and most likely 70 degrees above you...
If you have a chance to go back...try to make stories out of these photos...it shouldn't make a person looking at it go "That's a bush in front of a barn"...what did that bush and barn make you feel? It must have been something...it drew you to take a photo of it...now the why must be translated to the viewer...
