I can help BTA import some better-looking turrets.
Also, you can get trails from a lot of places. They're pretty easy to make in Photoshop, and if you don't have it, I hear there are some free alternatives available. Heck, with the right plugin, you can even open, edit, and save .dds files from photoshop.
If you just really, really like one of the ASW trails, I don't think the ASW team will mind if you use it, so long as you give them proper credit for it. In fact, credit for the third-screenshot cruiser model goes to the ASW team; all I did was the reskin.
BTA, we need to get you some PCS 2. Reskins are easy and fun! Which person was it that has the link to PCS 2 in their signature?
