Welcome to the froum. First impressions:
1) I think I might have cropped it closer to get rid of the out of focus (OOF) branches along the bottom, they are a bit distracting.
2) You either need a longer lens :mrgreen:, or you need to crop it a bit better to see the bird - if it is the subject of your image. I like that the colours are good and the tree bark is nice and sharp.
3) I'm a wildlife (animals, birds and flowers, etc) and macro guy, so I can't really comment on this one. It is sharp and the bokeh is good.
As far as sharing your images on the forum, a couple of things to consider - if you number your images, it makes it a lot easier for a reviewer to refer to them as they don't have to keep flipping back and forth to ensure that they are commenting on the right image. Also, if you could leave some space between your images, then viewing them as individual images is easier.
