A great subject that would probably look wonderful towards the start or end of the day - this looks like mid-day, blowing out the sky and leaving hard light
Nice detail in the trunk - would like to see the arms in full. Since you didn't show us the top, I'd suggest eliminating the bright sky area - distracts me from your main subject.
Purple fridging appearing at the top of the photo, where the sky has been overexposed and has no detail. I think if you shot this at about -1/3 or -2/3 EV, you can bring some details back.
