Rust Metal Texture

Tips on drawing textures (specifically Clean Metal, Rusted Metal, and Water)?
I’ve been drawing (self-taught) for a year now, and I’d say I’m fairly good. However, I’ve mostly been drawing people, and the occasional animal. I have plans on creating my own Graphic Novel, so I need to be able to draw textures and background.
what are some tips on drawing textures (specifically the ones listed in the main question) with a pencil?
(Youtube links are also appreciated)
Ah, I worked on several graphic novels in the past, which I never finished them, but I did learn something everytime. I assume you are looking for the Manga style of art, which I have some experience with. Those proved to be three challenging textures though.
Metal- Start out in pencil and retrace all the lines in ink of course. For a flat surface use steaks and washes. When it comes to metal it’s all about the shape and where the light source is. Manga usually has a defined art style as far as characters but when it comes to backgrounds it pretty much goes by how things naturally look. Metal usually has a lot of highlights and defined dark areas according to the shape. If it’s a dull metal then it’s just grey scale and doesn’t have any highlights. For every indention, edge, bend, there should be shadows complemented by highlights
Looks like their using a computer program in the video but it will give you an idea on shading.
Rusted Metal- Greyscale like a dull metal. The texture is really spotty and there are no highlights, but dark and light areas. Using a sponge with grey water color may work but make sure some to not apply it as heavy in some area since rust is such an uneven textures. Adding scratches or line streaks will give it more detail, also adding some pealing paint and defined rust areas.

Water- lay down a light gray tone, draw lines from side to side. Then take an eraser and pull out the parts of the waves which are reflecting sunlight. Anything around the water should shaded in the water, and I suggest smudging cause it makes the reflection look more “wet” also the reflection shadow should be wavy and fragmented the way it would naturally appear, if the water is real still, the reflection shadow should be still as well, and depending on where something is determines how long of a reflection is, for instance, if a tree is close to you in the picture, then it will have a longer reflection in the picture, trees further back will appear more stilted.
This might be a little to realistic but it’s the same idea.
Well, I haven’t drawn in a good while but I think those are the ways I used too.
