The difficulty with bald cypress is deciding what to do with the "chop". To get the buttress base you have on your tree, it was probably cut down from near 20 feet tall.
In nature, bald cypress get broken and topped. In an effort to help you plan, I took some photos from the Lower Cache River, in southern IL. In this watershed there are stands of bald cypress, mostly in discrete age groups. There is one ancient tree, 1300 years old dated by coring. Then there are around 50 trees estimated at 800 years old. (some cored, some not). Then there are several hundred trees that are roughly 400 to 500 years old, then the rest of the mixed forest is all trees less than 150 years old. The naturalist suggested that only in a few discrete years were conditions right for large numbers of seedlings to survive. So the trees in these stands tend to fall into discrete age groups, with few trees of "intermediate ages". Some combination of climate and river conditions, flooding, drought, and competition with other trees, allowed only certain age groups to become big trees.
This first photo, the tree on the right is probably near 800 years old. It had been broken off at about 15 feet tall, and 2 "back buds" have matured to to replace the top of the tree with 4 vertical trunks. That's one way to handle a chop. The tree on the left is in the 400 to 500 year age group and is a different way to handle a chop, with a single leader taking over.
The next is the oldest bald cypress in state of Illinois. Dated by coring, to be 1300 years old, actually, the photo is 30 years old, so add a little. The tree is still standing as my nephew took friends there last year.
Look at the crown of the tree, it clearly had been broken several times over the 1300 years. Also note that NONE of the bald cypress in the background have the exaggerated FLAT TOP. The "flat top" design advocated by some is an exaggeration of what happens in a few areas, in reality most bald cypress will go from a conifer type profile to a wide low dome, not really a "flat top" tree. So ignore suggestions telling you it has to be a flat top to be a "naturalistic style" for a bald cypress. Bald cypress really don't do "flat top" everywhere.
