For your first work not bad at all! You managed the form and shading pretty well, even if the arms be somewhat twisted/out of proportion, I don't think plain lines on eye shade/hair/softer and more subtle facial features works as well as softer edges, and that bra looks strangely blocky. Nice detail with the lights and flare though, and bubble with similar form. Maybe soon enough you'll get fans to do these for you too. :P Nice work.
