What lens are you shooting with? With the second picture I'd suggest maybe tweaking the color temperature - bringing it down to something a little bit cooler/closer to what our eye sees. I really like how the orange cast works for the first photo though.
the first one reminds me of a brisk summer morning the second is kindof trippy great job, im no photographer but these are fantabulace
diggin these pictures I like the first one, a nice silhouette of the leafs with a light peaking through the second one almost looks like an HDR nice job
