Looking at the reference I do not feel fond of my work...

Hope the added details will make it look better... Like... 100% better? Ahhh, I need to cheer up.
CHEER UP!
You can do it! You will do it. DO ITTTTTTTTTT!

nwjrun0975 Could you give me an advice for the colours of the branches?

!!

Gold? ? Red or
Silver and blue?

Ah, thank you very much! I was not sure if I could go with Gold/Silver (or pearly) or just some earth-colours. I love the blue colour you gave one branch. Hope I can get that tone too.
