Hi, DayZ has awesome graphics and potentional. I know, devs are making new ( or editing, i'm not sure ) engine so it'll be really cool to add some features :

• Water-drops on screen. ( It should only work in third person camera. For example when it's raining or when you're exiting water after pulling camera down in water. Picture : http://cloud-4.steamusercontent.com/ugc/530632224558139458/6349FEA879E8D99ACBD2F45ADFB93F87C1742109/ )
• Sun squares? I know, they added sun lighting through trees for example, but when looking closely in Screenshot, you can see some kind of bubbles or squares. That would give this game a little bit better experience of graphics. Screen shot : http://cloud-4.steamusercontent.com/ugc/530632224558139897/6789D1B4AA3FD590DC6DBE9DB984ECC1E6A988E2/ )

Also, let me know what suggestions about effects do you want me to add, I'll add them on your request.
