I'm not insulting you, I'm trying to give you constructive critisizms on getting better at customizing! Theres no need to get defensive. I understand that you're just starting out which is why I'm giving you tips on making your customs better!
This is really sloppy. I'm sorry but I'm not going to sugar coat this. You need to take more time with these and put in a lot more care and effort. Maybe use a smaller paintbrush to get finer details, use some sculpting tools if it's too hard to do with your hands. Or maybe try working with a bigger figure. That way you can get the details easier. I'm trying to say this as nicely as possible but this just isn't a good custom figure...
