Limba is improving for sure.
As for the 4-5 people in a sig, the reason most don't like doing it is cause we've been doing graphics for a really really, really long time now, and cutting out all the renders is too much effort.
Also, the max sig limit is 420 X 220. Limba, make sure you make the sigs by that size and no bigger.
You guys will have to resize the sigs, as both of yours are over the limit.
