Hi Josef,
Would you do me a favor? Google "Bloodgood Maple landscape tree".
And post us some pictures of what you like to see in your garden.
Then if you have your tree deliverd ,show us the tree, and some of us can point you to the direction of how to grow your tree of your liking in one of the pictures you showed.
Easer for us, as landscape tree's are not bonsai's. So most bonsai people, don't style landscape tree's. So i or we don't know what you want. But if you can give an example of what you have in mind. We might can point you to the right direction, how to grow it, how to cut it, how to get your results, in a estimated guess of years.
