Hi,
You're doing some good seeing and finding interesting things to photograph.
You need to pay closer attention to the lighting, for example a bright light in the background behind a spider will cause your camera to underexpose the spider. The difference between an amateur and professional photographer can be summed up in one sentence: An amateur looks through the camera and sees the thing they are photographing while a photographer looks through the camera and sees how that thing is lit. If you click the shutter release and haven't consciously thought about how the lighting will work in the photo you've made a mistake.
I don't want to discourage you, but here's a challenge for the future. You're using a typical consumer market camera that processes the photos you take to finished JPEGS. If you hang around here long enough you'll encounter Pros using cameras that save RAW files. Digital photography's dirty little secret is that camera image processors really don't work very well. The technical goal is to have a finished photo with correct tone distribution and correct color. There's nothing wrong with your camera; it just can't really do that job. My camera cost $4,000.00 and it's no better. So I and most Pros do the job ourselves manually. Your camera won't give you that option and it's going to screw-up a lot. So you have to learn to fix the tone and color screw-ups that your camera produces. Here's an example from your website:
Tone response: Your camera rendered the photo flat -- lacking contrast.
Color: Your camera made the photo way too blue and a little cyan.
As I said there's nothing wrong with your camera. If the engineers who design these things could make them work they would. The marketers in the meantime have decided that it's best not to tell the public the truth.
Fixing your photo was very easy. I used Photoshop and it took me a couple minutes at most. The hardest thing in this is learning to see what's wrong in the first place. That will come with practice. Folks here can help.
