Well first of all, I'd suggest some good old fanatics. Also, for a 1500pt list you have a lot of artillery. If you plan on moving things up to 2000pts I'd keep it, but otherwise you might want to drop a few pieces for a 1500pt game. The trolls you might want to bump them up to 3 Trolls and make them a full unit. One lone troll isn't going to do a lot, but 3 trolls might make the difference when it counts.

One lone troll isn't going to do a lot

I disagree, lone trolls are amazing deployment drops, blockers, flankers, speed-bumps, redirectors, anything. I'd definitely keep those as they are currently.
However, your army is absolutely tiny. You definitely need to free up some points from those warmachines and make your goblin and black orc units bigger. 30 goblins wont do much for long, they might tarpit something for 1 maybe two rounds but 50 is a much better size. Black Orcs should be at least 25 - 30 strong, 15 is just too small.
A doom diver and a mangler squig and dropping your shaman down to level 3 would give enough room for the 50 strong goblin unit and about 12 more black orcs.
IMO, this would vastly improve the list as you'd now have a fairly strong magic phase, a good tarpit unit, more than decent artillery and 2 very strong combat units. Instead of a very strong magic phase, great shooting, but only 1 good combat unit and 2 that will crumble against swordsmen...
Hope that helps.
