basically its depending on the style your looking for, but! I suggest working on realistic first so you'll know were to put everything etc. and I highly suggest looking at a reference (real life picks), but it looks really good and its all up to you.

good job!! ^.^

and im not the best artist, but these are my suggestions! (this one is more animated though)
