You should leave the model on the table a take a picture from there, instead of holding it up. Hands aren't usually welcome in pictures like these. Also, you may want to rotate your pictures so that it'll be easier for people to admire your painting as it should be, and not with their heads turned.
Having said that, the painting looks fine, if a little thick. So many colours serves to distract the viewer(me) from focusing on the model, so you might want to remedy that!
