`Hey, welcome

about the sigs:

1. nice job, it's good to see original stuff like that
2. could have been nice, but the bevel and embossed text ruins it (never use text with bevel and emboss)
Also, you could have done more on render blending
3. this could have been really nice! just blend the render a bit more, and it's ready
4. unfinished. got blending, but no effects
