Spirit of Africa Logo

It's been a loooonnng time since I attempted a logo design so thought I'd better make the effort to get back into it. This is a design for the Spirit of Africa (spiritofafrica.org.uk), it's an orphanage based in South Africa. I went with a caring angle, with the heart shape and adult (not sure if it's suggesting a parent though). Anyway, I know it probably needs work, especially the typography, but I've ran out of time and I need to update the UI design for the website.
