Well I can't say much about the body because imo although you have their ships present like in every combat scene later on they themselves aren't really shown at all except for Season 1 and as such imo are a rather unimportant faction and I can't say if they appear even in the background as from Season 1 (not too bad anyway as especially their introduction during that trial was kinda stupid anyway)... ^^

Well but what I CAN say is that you really didn't get the face / headshape right. Here the comparison (both from that trial scene afaik):



So with considering that you especially didn't hit the shape of the eyes which are very oval and way more wide than high. The head also has pretty much one solid "forehead-plate" with kind of big bumps on the sides - you created something which looks a bit like that Drazi headplate and that is this thing centered above the nose and forming an oval shape...

It's not a bad model though but it has those issues if you want to mimic the characters from the series...

Enjoy your meal
