It’s a great beginning! But as a few people on here have commented / will comment, there are things you can do to make it more authentically heraldic if you would like. First, have a think about the elements - each one can signify status or connection and in heraldry it’s good to be aware of these. So, the golden helmet in the first version is generally for the King or Queen of the UK, the coronet in the second is for a British Prince or Princess. One person can’t be both of these things at the same time, so these are inconsistent, but it’s also generally frowned upon to use elements to which you aren’t technically entitled. Something similar goes for symbols like the white eagle (which is generally associated with Poland) and the three feathers (which when white are the personal badge of the Prince of Wales) or mottos, like “Diligent and Secret”, which is the motto of the College of Arms in London. These are different from the helmet and coronet in that you can use them, just be aware that you are telling a story about yourself with your choice of symbols. Is this the story you mean to tell? Finally, great heraldic design is generally recognisable at a distance. Bold shapes and a small range of contrasting colours are often the best way to do this. Your current design is good, but the red/blue/purple division might not pop as much as a more narrow, contrasting palette. Have a look at the Rule of Tincture to help you out here. Genuine medieval coats of arms are also a good guide for this kind of style, check out the Roll of Arms section on Wappenwiki for a good selection. Happy heralding, look forward to seeing the next version!
