honestly i don't think it really similar to the real SPR-2, because i craft it from a PGM Hecate, included PeeWee.
known bugs 1.The laser misplaced if used right handed, but not left handed 2.There's some animation bug when reloading, and after 2 days i still can't fix it, if there's someone who can fix it please tell me :D
It's a good skin actually. But I do see a couple of those 'errors'. Not sure if that's what Sasek's referring to (I am blind to most compiling errors) the the hand seem to be clipping with the mag during reload.
The texture's contrast is a bit high for my taste. And it's mostly just black so while the texture does look good, it is kinda boring as well.
Reload is way too fast. But I guess that's because you ported this from another game (like CSS) and it had too many frames. I think you can reduce the fps from 51 to 48 though.
Other than those I could point out, it's still a good skin for me...
