The first two fakes of yours are quite simple, the first being a simple chatbox fake, easy to make with the Group Faking Kit (If you haven't noticed, RuneScape made humongous edits to NPC chatbox heads, revising or replacing just about all human images. I think you got Donie's face from Wolfiemario's NPC collection on the GFK, right? The old Group Faking Kit hasn't been edited for the new updates. The Group Faking Kit 2.0, however (

The second fake's "fake" part consists of only the word "noob." Although I kinda laughed, it won't really get high ratings from peoples.
I see your last fake is quite a bit more detailed, although the numbers for hitpoints/summoning/run energy/prayer points are in the wrong font. (Wolfie's fonts might help, although you probably should just take a screenshot from in-game.) The top bar (the one with the "Main Menu," "World Select, "World Map," and "Rules" links) makes it a bit obvious that this was based on a rather old faking kit or screenshot--you might consider making an updated version so trolls don't say things like "-999 old interface n00b," which is a quite unfortunate habit of less savory members of this forum.

I don't really get the point of this fake, though.

What does the "Sal's Realm" thing have to do with the NPC and assault rifle in the fake? It's quite simple--you took a screenshot of some other game and pasted the giant monster (is that the Corporeal Beast?) into the fake. You didn't do a really good job with the username "Sals Realm," as I can see the copy-paste lines. The minimap doesn't match up, either (I really can't blame you, what with the minimap updates that uses anti-aliasing and whatnot, but still...), so I suggest that your future fakes take place in RuneScape. Part of the minimap problem is the absence of scenery and buildings, but also I cannot see the little white square that's supposed to be your character (that's supposed to be in the center of the minimap--another reason for fakes to take place in RuneScape), and the yellow dot for the NPC is too far south (if that yellow dot indeed is the monster). There are many odd black lines at the bottom of the inventory (I presume they were part of a kit, but you didn't cover them up well), there's a few dark lines on the space where the summoning tab appears (where'd it come from?), and the Objectives and Notes systems are absent.

The items in your inventory are quite random (Are you soloing the Corporeal Beast in another game? Is that the point of the fake? If so, why is your food in notes? A suicide run?

), there's no cursor in the chatbox (although I'll allow you that, as the cursor blinks in and out), the Inventory tab is outdated, and you really should have cropped out the little white area along the bottom of the fake. I'll allow the "Created By: Wizard2k44" in the chatbox, as many fakers and faking groups use watermarks and images to make sure their fakes aren't ripped, but you should probably use a more permanent watermark. One could easily edit out that line, and images made semi-transparent pasted over a fake make editing it hard, while also marking it as your (and yours alone) property.
Wow, that was a long speech. I hope I didn't lose you there.

Don't take my criticism too seriously--we all start somewhere, and I'm not the best of fakers myself. I'll rate the third fake 5/10 (The other two are really too simple to deserve a rating, sorry.

) for the many errors, being lenient because you're kinda new here. Please keep on faking--the possibilities are endless!
