Looks nice man, I like the way you painted the paper. The wood on your guns looks good too.
The white is still a bit thick though, are you starting off on black? I'd recommend you first put down a layer of some kind of light brown first, it gives it a good shading and its easier to paint white over black. If you want it to look like "pure" white, then use a light blue such as GWs Space Wolves Blue.
I have an army with bright white as its main color and believe me you need to build to it, and possibly use two thin coats of white at the end instead of getting it all on at once, it's worth the extra bit of effort. I'd also recommend buying the P3 bright white (dunno what it's called), it covers very well and was a huge improvement over the GW pot I was using before.
