Welcome to the forum. Just one request, that if you are going to post more than one or two images, then could you please number them. This makes it a lot easier for a reviewer to refer to them. Thanks.
They all look a little overexposed, except possibly for the first one. In the rest of them, you have some significant "hotspots" or washed out areas. Also, watch your cropping. In the first two, you have cropped part of the flower's petals and in the last one, it appears that part of the spider's legs have been cropped off.
If you are just starting out, then you may want to read up on aspects of exposure and composition. For example, you can find a number of references to various aspects of composition here -
Photography Composition Articles Library. When it comes to exposure, Bryan Peterson's book - Understanding Exposure - 3rd Edition: How to Shoot Great Photographs with Any Camera -
http://www.amazon.com/Understanding...8- &keywords=bryan+peterson+photography+books is probably one of the better references around. HTH.
