macro - help with colour balance

I took these two recently, and although I am quite happy with them, I still have a niggle that the colour balance isn't quite right.

Can anyone pick it, or am I being too critical? Suggestions for improvement would be gratefully received

Hi there,

I like the photos!

i focused mainly on the second one,
the WB does seem a bit warm, i corrected it the way i saw was better for me, but thats just my opinion, if it seems better to you, just do the same on your first one,
slightly increase contrast, up the vibrance just a notch, reduce green (it will intensify the green in the photo actually), then just burn and dodge if you feel like it, to bring out colors you deem interesting.

I placed the two photos next to each other so you can compare better (excuse the quality reduction, i had only your jpeg to work with):

Nice pictures. A couple suggestions:
You need to clean your sensor.
The pictures look very noisy but were shot at low iso. You probably pushed the exposure a little too much. I would apply some noise reduction and sharpen them.
