I used one of Teyon's (the 3d modelling forum moderator) low poly base meshes to start with.
I loaded a project human mesh into wings and worked alongside it, so i could look at the topology of the other mesh. So I wouldn't say it is my own creation. It is more of a learning exercise.
I haven't done a lot of character modelling; and thought that would be a good way to go about learning. I've made some low poly game figures, but nothing very detailed.
