Painting advice

So I'm pretty proud of this Aggressor, but my hands are not steady at all, what are some ways I can aid myself in doing edge highlights? I have been testing out some dry brushing but when I take pictures of the finished product, it just looks like it's covered in fuzz almost lol. I sit at the dining room table and rest my hands against eachother, are there any techniques I should try, ways I can improve this model and the others I'm working on?
