No 1 has a nice composition, but the colours in the frame lack the punch. Maybe you might want to choose a more colourful framing. Tweaking the colours wil also help playing with the AB channels using LAB colourspace. The last one also is a nice composition idea. But again. boost the colours. Stock photos almost always need a tweak to give the shot a punch.
Thanks for the info, gonna play with the colours for a while. Always worried about over saturation, but I can see your point
