Good start but I will give you this advice, use the search function to get a basic idea of how some parts where made. Theres one of two choices, spend alot of money making props yourself, or spend alot of money buying them.
A mandalorian is one of the hardest costumes to create, it can be done on a budget if you take your time and realy focus on each piece one at a time.
The level of detail depends on comitment and desire, plus alot of time and money.
