@ s33on - you can take the advice and crits or leave it, its up to you man! i just think its important to understand what works and what doesnt, and people on the internet are real quick to tell you what doesnt. on the flip side, the better you get the more people will notice.
@ sadg - i'm digging the style on the second pic a lot, but on the R tighten up those arrows if you want to use em. on the bottom right its noticable that it will never come to a true point, work on making sure if it will be an arrow that it could potentially connect - even if its off the page.
