Composition is a bit too centered I would suggest you also try some better angles, when you try it again with a better sky ofcourse. Also this myght be helpful when figuring out an angle. IMHO the fact that is so centered makes it a bit boreing.
Thanks for your input; I agree with the point that the sky was flat and washed out. Especially with a bare tree and a lack of sharpness in the reds. I'll go back (assuming I can find it!) now that the tree should be fuller and green; a blue-green left side would contrast nicely with the red on the right. And I'll work on the framing for better balance of elements.
Thanks very much!
