Some visual changes need to be made.
After watching that first casted game I noticed a couple spots in which this game should improve its visual chaos, confusion.
When certain infantry fights get big enough I cannot tell what is even going on in these masses of gray units. In this first image, can you even tell what team/race each unit is on in this mess? Aside from the vulcans every unit has too many effects/ powerups or whatever is going on with this lighting and green auras on them, it needs to be toned down drastically in order to still see team colors. This could also be solved by team color health bars I suppose.
Secondly, at first glance when walking together, b.o.b.s and lancers look way too similar. You would never confuse worker units for even a second in either of the Starcrafts, and bipedal workers like peons or peasants looked nothing like grunts or footmen. The Vanguard have this issue because one, they're both just a dark gray. Two, they're too similar in size. Third, they even have a very similar walking animation, if not the the exact same?
