First of all, let me say that is some excellent work. Especially considering you did all free handed. I do have few questions; one where did you get the balsa wood? I am a carpenter and the lumber yards (not the big box stores) do no carry balsa wood. I wonder if ash would be close substitute? Popular seems to be a little to hard to carve out, even if it's still soft. Your reference pic, where did you get it from, and what scale did yu print it? Thank you for your time. Have a nice day.
