For each major camera brand, like Nikon or Canon, there is a user's forum on the internet. Sometimes that is more of a discussion group, and sometimes that is more of a photo-sharing group. Some are better than others.
No offense here, but if you are really a beginner, it would not hurt you to get into a photo-sharing group. You will see both good stuff and bad stuff, and if your eye can sort out the difference between the two, that is a start. Sometimes the intermediate users get into a discussion group. If you share some recent images, don't be afraid that they will tear you apart. At first, that happens.
Another approach is to shoot some stuff, and then print out the very best images with a good printer on good paper. Show those around to friends. After a while, you will learn which ones show good skills and which do not.
