Firstly, I'm not an artist, although I can do some basic models in Blender.
That being said, I believe some parts of your model are too much higher poly than others. For example, your model's fingers compared to the model overall: They are a very small part of the body - and, depending of the game type will use the character -, will be barely visible to be modelled with so many polygons on a somewhat low poly model as this character is.
Other point, is that the head seems too big for the body that have it (if it's not intentional).
Also, to me the model seems somewhat feminine (mainly the body's bottom half and head), but its chest isn't (I'm not talking about making them over-exaggerated like on most games for - sexist - female characters, just to be a bit more feminine than what it is now).
Those are my (hopefully constructive) impressions. I would recommend you to use some 3d references (like
this one, for example) as guide to create an humanoid model - which helps a lot on the process (you can google for some Blender tutorials on that). Anyway, as Julius said, it's much more easer to make furniture and other non-humanoid 3d models, and those are great ways to get some modelling skills with less-frustrating results (just as side note, I've tried to create humanoids for two or three times, and never got a barely usable result).
