the foundation logos are quite nice… would make a nice wallpaper with a little post & the bg maby something else than black.
some funny subsurf artifacts in the bloodcells… how did u model them? Otherways some more material to those things to make them seem translucent (not just plain transparent please)! also a little a bit movement + motionblur and u’re all set!
so nope not at all horrible but some tweaking could make them something more than just “not at all horrible”! 8)
the logo une is cool, but I don’t like the specular line on the leftmos hexagon of the foremost logo.
Bloodcells have subsurf problems, as noted by kruppa. This is due to the triangular faces you surely have there, you probably spinned the cell profile, right?
YOu should get rid of those tris or surround them with coplanar quads.
The blood cells is just circles whit some small extrude… I know that the cells aren’t perfect but I’m working on it… maybe whit planes and serious subdivide and subsurfing.
You should combine the two… make the Blender Foundation logo type dealy look like blood cells… the same texturing and stuff flowing through someones viens. It would be an interesting twist…
