When I started play CS:GO there were not so many weapon paints and one of my favorite one is AWP Graphite.
For now there are a lot of "loud" and bright skins in anime style and etc. but in goes out of reaity but Counter-Strike is about realism and men guns (I know that ladies like to play CS :D) but I think most part of players would like to see more classic skins with sence of realism. But this is only my opinion and honestly I also like to paint something bright and funny.
My be you finally look at my workshop and find something interesting for futher cases, because for now I left my job and comletely focused on CS skin making and hope that it pays me back :D
