Crystal,
Welcome!
Since our in-house critique machine, Mike Savad is on......a hiatus, I'll step in for him. You have a good eye and just need to practice more. The image that you posted is very GOOD!, but it out of focus and won't be printed if sold. If at all possible, try and re-shoot it. Are you using a camera or a Smart Phone Cam? Your images/files that have been uploaded, all seem very small,many are very contrasty and grainy or full of noise, which is also an issue for the printer.
Make sure you don't over saturate images and sharpen them to be uploaded, as the printer will sharpen them, later if a buyer orders one and over sharpening them before you upload will create issues, like contrast and grain.
The good news is of course that you DO have a good eye for photography and should pursue that goal and continue to challenge yourself to improve your art, regardless if it's for here or as a business for down the road,
Hope this helps and you can ask any questions and we'll try and answer them or you can email me directly,
Rich
