There are always two areas to consider (maybe more) - tool technique and comfort, and design. A local wood turning group can be an enormous aid in both.
For a first effort, the turning is way beyond typical. One observation, can't tell from the picture but the top might be flat. Some will try to make the top gently rounded, some will prefer flat.
Don't hesitate to sketch out possible designs on paper - set yourself a goal to make 5 or 10 different ones. You are limited on the bottom diameter, but you could make some different lengths, wider diameter at the top, curve out and then in again, . . . - they don't have to be equally functional, just start to explore. Poplar or even a piece of 2x2 is excellent wood to gain experience and comfort with tools and to try different designs, as one doesn't worry about the cost of the wood.
