those logos looks really nice.
but i guess wold be better if you use other program as Blender 3d,or 3D studio/maya.
you did some hard-detailled 3d stuff.
Team fortress 3d logo was for real awesome,nothing to say.
CS:GO was good,yet again,the details was awesome.
in the toribash logo i guess you wold just put a circle in the back of the symbol,and the symbol wold be in black.
but these are some good stuff,keep doing it.
