I find the sky a bit distracting in the top corner. Zooming in, moving closer to the subject or cropping could remove it though. Be careful of the focus: the main leaf my eye gets drawn to is quite soft and could be sharper.

I love all the autumnal colours, the different shades of reds, browns and greens. Perhaps a touch more saturation could help bring those colours out even more.

yeah, luckily with the high resolution of my new camera I can now crop :)

For whatever reason the colours appear brighter on the camera screen than on the computer screen

Most image editing software will allow you to make colour adjustments. If you use that and follow some video tutorials online about post processing, it can make a huge amount of difference to a picture (in moderation of course!) Good luck!
