New to Bonsai

Hello All! I am very new to bonsai, and my trees are all seedlings. All are just under three weeks old. I am trying four differents styles and am hoping for success. Four out of four of my bristle comb seedlings have started amazingly so far. Three out of three of my black spruce have started, but they are so fragile I think it is too early to judge. I am not sure about my flame tree and rosewood ones yet because I have not seen any signs of germination yet. I'm going to try to repot the bristle combs as they are all now about three inches tall and were started in the same small pot. Any words of wisdom or help along my journey will be much appreciated.

Working with seedlings is super fun indeed. But if you are a beginner that want to get into bonsai you are now 20 years from that. Get yourself more mature material to work with, if not you will most likelly torture your small seedlings long before they are ready. Beeing inpatient is a part of beeing a beginner, Believe me, I am still.
