i believe this is the newest one correct?
well heres what i can say about it based from pics
well im gonna attack the lighting again....all im gonna say is more can be done with it
also it looks to me as if your bases lighting (Nod being red and GDI being gold) are lighted from Invis red or yellow lamps.......is that how you did it? cause if so you should use the afterglow script which makes Nod buildings glow red and GDI glow gold. i think OrcaCommander had a fix for that cause i dont think it works properly without the fix.
looks decent but it does look a little crowded like you said. usually on small maps you either play with a low tech or you get right into the primary objective and straight into the battle itself pretty much.
seriously take the time you have left which is a little over 2 weeks and make a SMMC map. i suggest you go read its thread to get more info on it though if you havent already. because there is valuable info there which would make your map better.
anyways good job. just keep practicing you will get better.
