For contacting me, use my personal email email@example.com. I check my email all the time so there won't be any delays in responses.
For payments I suggest to people to use Transferwise, because it's really fast and they charge you very little in case you're paying in another currancy (I accept money in Sterling Pounds - GBP).
Please, make sure you send the right amount,considering the exchange rates.
I always charge only the base price that is 25$ (aprox. £18,84). I only charge extra 9$/hour if you are considering to buy a really complex and detailed illustration that takes me longer than usual to finish/ more materials
