I like the composition in the first two the colors arent really popping to me but its a nice shot.. the last two dont really say anything to me at all the third is too close imo and lacking somethng.
At 1024px wide these are too large for web-presentation.
Make sure you downsize your photos to a max of 800 px wide (when they are a horizontal format) or 800 px long (when they are a vertical format), please.
They could do with a run through a pp software to make them develop their full potential. Nice weir.
