Good art BUT
Someone thinks the buttons don't work cos you didn't put a proper hit area behind them, so they only work when you click exactly on the text instead of a nice rectangle.
You put a lot of work into the guns but you let yourself down by using very poor english. Get someone to help you edit it.
To make this a really useful tut you could get info on the guns so people could use them accurately. If that is hard, then get someone to help, maybe from the forums.
"This is a Spik 32, its made in Lithuania and is a small, light semi, well known on the black market. Use it for terrorists and bank robbers"
"This is a Margon 360. Its a heavy rifle not much seen outside Nato forces in Europe. Use this for regular Nato soldiers"
Put in a couple of links that would show background and development of your subject and you would appeal to a much wider audience, instead of just being a source of good-looking guns for stick men.
