Hi Ascor,
Some nice trees. Howa re you faring with the styling? As for advice: No advice but some ideas; which you probably have yourself with these trees too..?
The first I would probably turn into a 'young and healthy' double trunc, where the canopy of the smaller trunc would pretty much be the lowest section of the biggest tree.
The second I could see as an very old multi-trunc tree, with a lot of deadwood, and only incidental branches on it. Basically mainly bleached wood, a few strips of red-brown living bark remaining leading to 2 or 3 living branches per 'trunc'. The main problem would be to get some more foliage closer to the trunc as it looks like it has lost foliage over the first few cm on the side-branches?
