well considring that im pretty new my self id say your doing ok , one bit of advise that i found make making models good is get the base down, which you have done then pick one part and slowly but surely work out from there , i my self get moders block when working all the time as i like big robots and such and want to put 15 gagilion things in , its at this time my brain crashes and i fall into a coma so dont do it that way
