Welcome to EPZ Andrew. The Critique Gallery is a good place to learn, and get honest feedback.
You ask a question that has some strings attached. Is it a good shot for someone who has only had 4 months with a DSLR and is still getting to grips with settings.
Lets ask, "is it a good shot", and the answer is no, not really, and I will get into detail about why in a minute.
If Im asked, "Is this a decent effort by someone that is learning and getting used to the camera" then the answer is yes, it is. You have done a lot right. You got down to the right level for the shot and you found a good subject. You made sure the camera was solid and steady, with no camera shake.
This is a difficult shot for experienced shooters.
Lets look at HOW you can make this a great shot. Things you need to know when taking this, and almost any shot.
First, the EXIF data does not have you cameras MODE, whether than Auto, P, A, S or M? I will assume its A or P, both auto modes.
The single, most significant issue with the shot that could be improved is the point where you focused. Look very closely at the small plants in front of the toadstools, and you will see they are quite sharp, showing that the camera focused in front of the toadstools. You can control this, especially in close shots, by using manual focus, not auto focus. Its pretty difficult to do this down this low, but it can be done.
Next is exposure, - the amount of light the camera captured for this image. Its underexposed, meaning that the shutter could have been open longer. After you take any shot, ply it back on the LCD and look at the histogram, - the graph; if its not extending towards the right, its underexposed; if it bunches up at the right edge, ts overexposed. Then you can take the shot again, and use Exposure Compensation, - check you manual, - its easy to do.
Thats mainly it. Good that you selected white balance yourself, - though I wounder if shade would be a better choice?
I uploaded a modification, scroll up, click the tab, and view the mod large, - mine is the second one. I have increased exposure and tweaked white balance. cant do anything about the toadstools not being in focus, but hopefully, when its brighter like this its easier to see where you did focus.
One final point. To get that area of sharpness to be deeper that it is, i.e to extend further towards the toadstools you use a smaller aperture. Thats the f number, and smaller means a larger number, so f/5.6 is bigger than f/11 as an example.
