definitely, you use the wrong tools. i seriously recommend you a deeper look at wings3d, blender3d or, if you can afford it, c4d.

to be honest, my "first" models looked even uglier, then i discovered wings3d and look at my latest artworks and judge: it's only a matter of tools, time, and creativity.
if you weren't creative, you'd have a different hobby.
if you hadn't time, you wouldn't sit down for 1:45.
what's left? the tool. don't waste your time with MED or Milkshape for basic modelling, really.

it's all meant serious and i hope it will help you.
