if its something you work on, and will continue working on and want to share, then WIP is the forum, never the less the quality ..
In this case its a nice piece of promissing work for a first timer.. so keep posting images as you work on the model and grant experience from others comments.
To comment your model :
Something strange is going on in the eye area,
what are those cylinders doing? ,
You have some creasing going on in the center of the head and the body, you should try to smooth that out.
Always model in a neutral pose, and pose it later when the model is finished.
