A comment - please number your images, as it makes it a lot easier to refer to them. In general, watch your cropping to make sure you don't crop off the ends of appendages as you did in the first and third ones. Also, watch your background so that you don't "lose" the main subject in it, as is almost the case in the last one. The third one is the best, in my opinion, despite the cropping of the leg. It shows good colour and the outline of the web is well defined.
