Different wrightia religosa

My small sized white wrightia religosa in leafless phase. Probably 8 years old and I've done a little branch trimming to ensure it tapers well from the root base towards the tip of the tree. Yet to win any award.



My rare medium sized yellow wrightia religosa. Obvious white body trunk but dark trunks? Well, I grafted all the main branches with yellow flower species. Bonsai experts...please help me to improve it. Gracias!

both of them are very beautiful, but I prefer the small one to middle one
for small : by the photo, at the behind top part is it defendant?
thank for sharing, well done, keep them up . I love them
