Sig: WW2 theme - CnC

Im still reletively new to graphic design and sig making so yerh. I do believe im lacking some good backgrounds. Anybody know where i could get a pack or something? Anyways here is my sig CnC and rate please.

needs a lot of work lighting placement colours don't look very good follow some tutorials I can link you to some beginner ones if you like

Eh, practice will only make you better. Think a green kind of like background would have looked better.
