Mostly yes. But of course there is a tradeoff between image quality and number of triangles. What should be avoided is to have vertices in straight areas or in the middle of single colored area (I can see several instances of this in your designs, remember that one more vertex=one more triangle!).
Number of triangles attached to a vertex is not a problem as long as you don't have extremely pointy triangles (see http://www.ldraw.org/article/512.html#colinear). But Datheader will warn you if that happens.
Overall I think that the LQ version is good (resolution wise). The 4 dots around the screen and the bottom of the dial are a bit coarse though.
Maybe you should use more the LDPC disc primitives, the vertices in your circles don't seem to be evenly distributed.
Thank you very much philo,
regarding the primitives, i did used them and then made some avegage of the points. i was testing only the tool , after i did realized that i spent lots of hour on making this usless part lolol
again thank you very much for all the recommendations,.
