Chair
 

here is a chair made

Yep, that's a chair! ;)

Maybe a better texture? It looks a bit grainy at the moment.

Indeed!

Maybe some more texturing wouldent go amiss, and maybe some render work?

im not that good at either of those so could you guys give me some help if you can thanks

One thing that helps make the model look even better is to give it some lighting.

Unfortunately I haven't really done much texturing or rendering myself, so I am not much help, but I would definitely start with mtmkinley's free texturing basics tutorial on this site and then I would read as much as I can on the UV texture editor as this is what will help you texture your model.

Hope this helps.
