I think the model is okay (not the polycount buts not important by training you skills this come with time) but you must know a good model cant hide a bad texture, thats the first think you always need to know when you make a model. Try to search pics from oblivion or gothic3 or what ever and use them for your first works than you understand where you can reduce polygones and so on...

Go on train and dont give up ;-)
your on good way

DoC..
