Recomendation about amount of triangles.

grrrrrrrrr.......

Yes it's painful... dunno if that can console you, but I've done it several times!!!

regarding this issue for future designs. the idea its to make the patterns with the less ammount of triangles as possible ?

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!).

any recommendation to add? in the LQ version of the pattern you can see some vertex have TONS of triangles that are attached to them. its this ok? or its not recommended to have many triangles attached to a vertex?

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.
